@@ -18,163 +14,58 @@ https://docs.github.com/en/get-started/quickstart/fork-a-repo
 
 ## Development Installation
 
+If you don't have direct access to push to mermaid repositories, make a fork first. Then clone. Or clone directly from mermaid-js:
+
 ```bash
 git clone git@github.com:mermaid-js/mermaid.git
 cd mermaid
+```
+
+Install required packages:
+
+```bash
 # npx is required for first install as volta support for pnpm is not added yet.
 npx pnpm install
 pnpm test
 ```
 
-## Committing code
+### Docker
 
-We make all changes via pull requests. As we have many pull requests from developers new to mermaid, the current approach is to have _knsv, Knut Sveidqvist_ as a main reviewer of changes and merging pull requests. More precisely like this:
-
-- Large changes reviewed by knsv or other developer asked to review by knsv
-- Smaller low-risk changes like dependencies, documentation, etc. can be merged by active collaborators
-- Documentation (updates to the `package/mermaid/src/docs` folder is also allowed via direct commits)
-
-To commit code, create a branch, let it start with the type like feature or bug followed by the issue number for reference and some describing text.
-
-One example:
-
-`feature/945_state_diagrams`
-
-Another:
-
-`bug/123_nasty_bug_branch`
-
-## Committing documentation
-
-Less strict here, it is OK to commit directly in the `develop` branch if you are a collaborator.
-
-The documentation is written in **Markdown**. For more information about Markdown [see the GitHub Markdown help page](https://help.github.com/en/github/writing-on-github/basic-writing-and-formatting-syntax).
-
-### Documentation source files are in [`/packages/mermaid/src/docs`](packages/mermaid/src/docs)
-
-The source files for the project documentation are located in the [`/packages/mermaid/src/docs`](packages/mermaid/src/docs) directory. This is where you should make changes.
-The files under `/packages/mermaid/src/docs` are processed to generate the published documentation, and the resulting files are put into the `/docs` directory.
-
-After editing files in the [`/packages/mermaid/src/docs`](packages/mermaid/src/docs) directory, be sure to run `pnpm install` and `pnpm run --filter mermaid docs:build` locally to build the `/docs` directory.
-
-```mermaid
-flowchart LR
-  classDef default fill:#fff,color:black,stroke:black
-
-  source["files in /packages/mermaid/src/docs\n(changes should be done here)"] -- automatic processing\nto generate the final documentation--> published["files in /docs\ndisplayed on the official documentation site"]
+If you are using docker and docker-compose, you have self-documented `run` bash script, which is a convenient alias for docker-compose commands:
 
+```bash
+./run install # npx pnpm install
+./run test # pnpm test
 ```
 
-You can use `note`, `tip`, `warning` and `danger` in triple backticks to add a note, tip, warning or danger box.
-Do not use vitepress specific markdown syntax `::: warning` as it will not be processed correctly.

+## Documentation
 
-````
+Documentation is necessary for all non bugfix/refactoring changes.
+
+Only make changes to files are in [`/packages/mermaid/src/docs`](packages/mermaid/src/docs)
 
 **_DO NOT CHANGE FILES IN `/docs`_**
 
-### The official documentation site
-
-**[The mermaid documentation site](https://mermaid-js.github.io/mermaid/) is powered by [Vitepress](https://vitepress.vuejs.org/), a simple documentation site generator.**
-
-If you want to preview the whole documentation site on your machine:
-
-```sh
-cd packages/mermaid
-pnpm i
-pnpm docs:dev
-```
-
-You can now build and serve the documentation site:
-
-```sh
-pnpm docs:serve
-```
-
-## Branching
-
-Going forward we will use a git flow inspired approach to branching. So development is done in develop, to do the development in the develop.
-
-Once development is done we branch a release branch from develop for testing.
-
-Once the release happens we merge the release branch to master and kill the release branch.
-
-This means... **branch off your pull request from develop**
-
-## Content of a pull request
-
-A new feature has been born. Great! But without the steps below it might just ... fade away ...
-
-### **Add unit tests for the parsing part**
-
-This is important so that, if someone else does a change to the grammar that does not know about this great feature, gets notified early on when that change breaks the parser. Another important aspect is that without proper parsing tests refactoring is pretty much impossible.
-
-### **Add e2e tests**
-
-This tests the rendering and visual appearance of the diagram. This ensures that the rendering of that feature in the e2e will be reviewed in the release process going forward. Less chance that it breaks!
-
-To start working with the e2e tests, run `pnpm run dev` to start the dev server, after that start cypress by running `pnpm exec cypress open` in the mermaid folder.
-
-The rendering tests are very straightforward to create. There is a function imgSnapshotTest. This function takes a diagram in text form, the mermaid options and renders that diagram in cypress.
-
-When running in ci it will take a snapshot of the rendered diagram and compare it with the snapshot from last build and flag for review it if it differs.
-
-This is what a rendering test looks like:
-
-```javascript
-it('should render forks and joins', () => {
-  imgSnapshotTest(
-    `
-    stateDiagram
-    state fork_state <<fork>>
-      [*] --> fork_state
-      fork_state --> State2
-      fork_state --> State3
-
-      state join_state <<join>>
-      State2 --> join_state
-      State3 --> join_state
-      join_state --> State4
-      State4 --> [*]
-    `,
-    { logLevel: 0 }
-  );
-  cy.get('svg');
-});
-```
-
-### **Add documentation for it**
-
-Finally, if it is not in the documentation, no one will know about it and then **no one will use it**. Wouldn't that be sad? With all the effort that was put into the feature?
-
-The source files for documentation are in `/packages/mermaid/src/docs` and are written in markdown. Just pick the right section and start typing. See the [Committing Documentation](#committing-documentation) section for more about how the documentation is generated.
-
-#### Adding to or changing the documentation organization
-
-If you want to add a new section or change the organization (structure), then you need to make sure to **change the side navigation** in `mermaid/src/docs/.vitepress/config.js`.
-
-When changes are committed and then released, they become part of the `master` branch and become part of the published documentation on https://mermaid-js.github.io/mermaid/
-
-## Last words
-
-Don't get daunted if it is hard in the beginning. We have a great community with only encouraging words. So if you get stuck, ask for help and hints in the slack forum. If you want to show off something good, show it off there.

 Here are a few things to get you started on the right path.
 
-**The Docs Structure is dictated by [.vitepress/config.ts](https://github.com/mermaid-js/mermaid/blob/develop/packages/mermaid/src/docs/.vitepress/config.ts)**.
+## Technical Requirements and Setup
 
-**Note: Commits and Pull Requests should be directed to the develop branch.**
+### Technical Requirements
 
-## Branching
+These are the tools we use for working with the code and documentation.
 
-Mermaid uses a [Git Flow](https://guides.github.com/introduction/flow/)–inspired approach to branching. So development is done in the `develop` branch.
+- [volta](https://volta.sh/) to manage node versions.
+- [Node.js](https://nodejs.org/en/). `volta install node`
+- [pnpm](https://pnpm.io/) package manager. `volta install pnpm`
+- [npx](https://docs.npmjs.com/cli/v8/commands/npx) the packaged executor in npm. This is needed [to install pnpm.](#2-install-pnpm)
 
-Once development is done we branch a `release` branch from `develop` for testing.
+Follow [the setup steps below](#setup) to install them and verify they are working
 
-Once the release happens we merge the `release` branch with `master` and kill the `release` branch.
+### Setup
 
-This means that **you should branch off your pull request from develop** and direct all Pull Requests to it.
+Follow these steps to set up the environment you need to work on code and/or documentation.
+
+#### 1. Fork and clone the repository
+
+In GitHub, you first _fork_ a repository when you are going to make changes and submit pull requests.
+
+Then you _clone_ a copy to your local development machine (e.g. where you code) to make a copy with all the files to work with.
+
+[Here is a GitHub document that gives an overview of the process.](https://docs.github.com/en/get-started/quickstart/fork-a-repo)
+
+#### 2. Install pnpm
+
+Once you have cloned the repository onto your development machine, change into the `mermaid` project folder so that you can install `pnpm`. You will need `npx` to install pnpm because volta doesn't support it yet.
+
+Ex:
+
+```bash
+# Change into the mermaid directory (the top level director of the mermaid project repository)
+cd mermaid
+# npx is required for first install because volta does not support pnpm yet
+npx pnpm install
+```
+
+#### 3. Verify Everything Is Working
+
+Once you have installed pnpm, you can run the `test` script to verify that pnpm is working _and_ that the repository has been cloned correctly:
+
+```bash
+pnpm test
+```
+
+The `test` script and others are in the top-level `package.json` file.
+
+All tests should run successfully without any errors or failures. (You might see _lint_ or _formatting_ warnings; those are ok during this step.)
+
+### Docker
+
+If you are using docker and docker-compose, you have self-documented `run` bash script, which is a convenient alias for docker-compose commands:
+
+```bash
+./run install # npx pnpm install
+./run test # pnpm test
+```
 
 ## Contributing Code
 
-We make all changes via Pull Requests. As we have many Pull Requests from developers new to mermaid, we have put in place a process, wherein _knsv, Knut Sveidqvist_ is the primary reviewer of changes and merging pull requests. The process is as follows:
+The basic steps for contributing code are:
 
-- Large changes reviewed by knsv or other developer asked to review by knsv
-- Smaller, low-risk changes like dependencies, documentation, etc. can be merged by active collaborators
-- Documentation (we encourage updates to the `/packages/mermaid/src/docs` folder; you can submit them via direct commits)
+```mermaid-example
+graph LR
+    git[1. Checkout a  git branch] --> codeTest[2. Write tests and code] --> doc[3. Update documentation] --> submit[4. Submit a PR] --> review[5. Review and merge]
+```
 
-When you commit code, create a branch with the following naming convention:
+```mermaid
+graph LR
+    git[1. Checkout a  git branch] --> codeTest[2. Write tests and code] --> doc[3. Update documentation] --> submit[4. Submit a PR] --> review[5. Review and merge]
+```
 
-Start with the type, such as **feature** or **bug**, followed by the issue number for reference, and a text that describes the issue.
+1.  **Create** and checkout a git branch and work on your code in the branch
+2.  Write and update **tests** (unit and perhaps even integration (e2e) tests) (If you do TDD/BDD, the order might be different.)
+3.  **Let users know** that things have changed or been added in the documents! This is often overlooked, but _critical_
+4.  **Submit** your code as a _pull request_.
+5.  Maintainers will **review** your code. If there are no changes necessary, the PR will be merged. Otherwise, make the requested changes and repeat.
 
-**One example:**
+### 1. Checkout a git branch
 
-`feature/945_state_diagrams`
+Mermaid uses a [Git Flow](https://guides.github.com/introduction/flow/)–inspired approach to branching.
 
-**Another example:**
+Development is done in the `develop` branch.
 
-`bug/123_nasty_bug_branch`
+Once development is done we create a `release/vX.X.X` branch from `develop` for testing.
 
-## Contributing to Documentation
+Once the release happens we add a tag to the `release` branch and merge it with `master`. The live product and on-line documentation are what is in the `master` branch.
 
-If it is not in the documentation, it's like it never happened. Wouldn't that be sad? With all the effort that was put into the feature?
+**All new work should be based on the `develop` branch.**
 
-The docs are located in the `src/docs` folder and are written in Markdown. Just pick the right section and start typing. If you want to propose changes to the structure of the documentation, such as adding a new section or a new file you do that via **[.vitepress/config.ts](https://github.com/mermaid-js/mermaid/blob/develop/packages/mermaid/src/docs/.vitepress/config.ts)**.
+**When you are ready to do work, always, ALWAYS:**
 
-> **All the documents displayed in the GitHub.io page are listed in [.vitepress/config.ts](https://github.com/mermaid-js/mermaid/blob/develop/packages/mermaid/src/docs/.vitepress/config.ts)**.
+1.  Make sure you have the most up-to-date version of the `develop` branch. (fetch or pull to update it)
+2.  Check out the `develop` branch
+3.  Create a new branch for your work. Please name the branch following our naming convention below.
 
-The contents of <https://mermaid-js.github.io/mermaid/> are based on the docs from the `master` branch. Updates committed to the `master` branch are reflected in the [Mermaid Docs](https://mermaid-js.github.io/mermaid/) once released.
+We use the follow naming convention for branches:
 
-## How to Contribute to Documentation
+```text
+   [feature | bug | chore | docs]/[issue number]_[short description using dashes ('-') or underscores ('_') instead of spaces]
+```
 
-We are a little less strict here, it is OK to commit directly in the `develop` branch if you are a collaborator.
+- The first part is the **type** of change: a feature, bug, chore, or documentation change ('docs')
+- followed by a _slash_ (which helps to group like types together in many git tools)
+- followed by the **issue number**
+- followed by an _underscore_ ('\_')
+- followed by a short text description (but use dashes ('-') or underscores ('\_') instead of spaces)
 
-The documentation is located in the `src/docs` directory and organized according to relevant subfolder.
+If your work is specific to a single diagram type, it is a good idea to put the diagram type at the start of the description. This will help us keep release notes organized: it will help us keep changes for a diagram type together.
 
-The `docs` folder will be automatically generated when committing to `src/docs` and should not be edited manually.
+**Ex: A new feature described in issue 2945 that adds a new arrow type called 'florbs' to state diagrams**
 
-We encourage contributions to the documentation at [mermaid-js/mermaid/src/docs](https://github.com/mermaid-js/mermaid/tree/develop/packages/mermaid/src/docs). We publish documentation using GitHub Pages with [Docsify](https://www.youtube.com/watch?v=TV88lp7egMw&t=3s)
+`feature/2945_state-diagram-new-arrow-florbs`
 
-### Add Unit Tests for Parsing
+**Ex: A bug described in issue 1123 that causes random ugly red text in multiple diagram types**
+`bug/1123_fix_random_ugly_red_text`
 
-This is important so that, if someone that does not know about this great feature suggests a change to the grammar, they get notified early on when that change breaks the parser. Another important aspect is that, without proper parsing, tests refactoring is pretty much impossible.
+### 2. Write Tests
 
-### Add E2E Tests
+Tests ensure that each function, module, or part of code does what it says it will do. This is critically
+important when other changes are made to ensure that existing code is not broken (no regression).
 
-This tests the rendering and visual appearance of the diagrams. This ensures that the rendering of that feature in the e2e will be reviewed in the release process going forward. Less chance that it breaks!
+Just as important, the tests act as _specifications:_ they specify what the code does (or should do).
+Whenever someone is new to a section of code, they should be able to read the tests to get a thorough understanding of what it does and why.
+
+If you are fixing a bug, you should add tests to ensure that your code has actually fixed the bug, to specify/describe what the code is doing, and to ensure the bug doesn't happen again.
+(If there had been a test for the situation, the bug never would have happened in the first place.)
+You may need to change existing tests if they were inaccurate.
+
+If you are adding a feature, you will definitely need to add tests. Depending on the size of your feature, you may need to add integration tests.
+
+#### Unit Tests
+
+Unit tests are tests that test a single function or module. They are the easiest to write and the fastest to run.
+
+Unit tests are mandatory all code except the renderers. (The renderers are tested with integration tests.)
+
+We use [Vitest](https://vitest.dev) to run unit tests.
+
+You can use the following command to run the unit tests:
+
+```sh
+pnpm test
+```
+
+When writing new tests, it's easier to have the tests automatically run as you make changes. You can do this by running the following command:
+
+```sh
+pnpm test:watch
+```
+
+#### Integration/End-to-End (e2e) tests
+
+These test the rendering and visual appearance of the diagrams.
+This ensures that the rendering of that feature in the e2e will be reviewed in the release process going forward. Less chance that it breaks!
 
 To start working with the e2e tests:
 
-1.  Run `pnpm run dev` to start the dev server
-2.  Start **Cypress** by running `pnpm exec cypress open` in the **mermaid** folder.
+1.  Run `pnpm dev` to start the dev server
+2.  Start **Cypress** by running `pnpm cypress:open`.
 
 The rendering tests are very straightforward to create. There is a function `imgSnapshotTest`, which takes a diagram in text form and the mermaid options, and it renders that diagram in Cypress.

+**_\[TODO - running the tests against what is expected in development. ]_**
 
-After logging in at [GitHub.com](https://www.github.com), open or append to an issue [using the GitHub issue tracker of the mermaid-js repository](https://github.com/mermaid-js/mermaid/issues?q=is%3Aissue+is%3Aopen+label%3A%22Area%3A+Documentation%22).

-### How to Contribute a Suggestion
+### 3. Update Documentation
+
+If the users have no way to know that things have changed, then you haven't really _fixed_ anything for the users; you've just added to making Mermaid feel broken.
+Likewise, if users don't know that there is a new feature that you've implemented, it will forever remain unknown and unused.
+
+The documentation has to be updated to users know that things have changed and added!
+
+We know it can sometimes be hard to code _and_ write user documentation.
+
+Our documentation is managed in `packages/mermaid/src/docs`. Details on how to edit is in the [Contributing Documentation](#contributing-documentation) section.
+
+Create another issue specifically for the documentation.\
+You will need to help with the PR, but definitely ask for help if you feel stuck.
+When it feels hard to write stuff out, explaining it to someone and having that person ask you clarifying questions can often be 80% of the work!
+
+When in doubt, write up and submit what you can. It can be clarified and refined later. (With documentation, something is better than nothing!)
+
+### 4. Submit your pull request
+
+**\[TODO - PR titles should start with (fix | feat | ....)]**
+
+We make all changes via Pull Requests (PRs). As we have many Pull Requests from developers new to Mermaid, we have put in place a process wherein _knsv, Knut Sveidqvist_ is in charge of the final release process and the active maintainers are in charge of reviewing and merging most PRs.
+
+- PRs will be reviewed by active maintainers, who will provide feedback and request changes as needed.
+- The maintainers will request a review from knsv, if necessary.
+- Once the PR is approved, the maintainers will merge the PR into the `develop` branch.
+- When a release is ready, the `release/x.x.x` branch will be created, extensively tested and knsv will be in charge of the release process.
+
+**Reminder: Pull Requests should be submitted to the develop branch.**
+
+## Contributing Documentation
+
+**_\[TODO: This section is still a WIP. It still needs MAJOR revision.]_**
+
+If it is not in the documentation, it's like it never happened. Wouldn't that be sad? With all the effort that was put into the feature?
+
+The docs are located in the `packages/mermaid/src/docs` folder and are written in Markdown. Just pick the right section and start typing.
+
+The contents of [mermaid.js.org](https://mermaid.js.org/) are based on the docs from the `master` branch.
+Updates committed to the `master` branch are reflected in the [Mermaid Docs](https://mermaid.js.org/) once published.
+
+### How to Contribute to Documentation
+
+We are a little less strict here, it is OK to commit directly in the `develop` branch if you are a collaborator.
+
+The documentation is located in the `packages/mermaid/src/docs` directory and organized according to relevant subfolder.
+
+The `docs` folder will be automatically generated when committing to `packages/mermaid/src/docs` and **should not** be edited manually.
+
+```mermaid-example
+flowchart LR
+  classDef default fill:#fff,color:black,stroke:black
+
+  source["files in /packages/mermaid/src/docs\n(changes should be done here)"] -- automatic processing\nto generate the final documentation--> published["files in /docs\ndisplayed on the official documentation site"]

+
+  source["files in /packages/mermaid/src/docs\n(changes should be done here)"] -- automatic processing\nto generate the final documentation--> published["files in /docs\ndisplayed on the official documentation site"]
+
+```
+
+You can use `note`, `tip`, `warning` and `danger` in triple backticks to add a note, tip, warning or danger box.
+Do not use vitepress specific markdown syntax `::: warning` as it will not be processed correctly.
+
+````

+
+````
+
+> **Note**
+> If the change is _only_ to the documentation, you can get your changes published to the site quicker by making a PR to the `master` branch.
+
+We encourage contributions to the documentation at [packages/mermaid/src/docs in the _develop_ branch](https://github.com/mermaid-js/mermaid/tree/develop/packages/mermaid/src/docs).
+
+**_DO NOT CHANGE FILES IN `/docs`_**

+### Documentation organization: Sidebar navigation
+
+If you want to propose changes to how the documentation is _organized_, such as adding a new section or re-arranging or renaming a section, you must update the **sidebar navigation.**
+
+The sidebar navigation is defined in [the vitepress configuration file config.ts](../.vitepress/config.ts).

 # Integrations
 
+## Recommendations
+
+### File Extension
+
+Applications that support mermaid files [SHOULD](https://datatracker.ietf.org/doc/html/rfc2119#section-3) use `.mermaid` or `.mmd` file extensions.
+
+### MIME Type
+
+The recommended [MIME type](https://www.iana.org/assignments/media-types/media-types.xhtml) for mermaid media is `text/vnd.mermaid`.
+
+[IANA](https://www.iana.org/) recognition pending.
+
+---
+
 The following list is a compilation of different integrations and plugins that allow the rendering of mermaid definitions within other applications.
 
 They also serve as proof of concept, for the variety of things that can be built with mermaid.

 Here are a few things to get you started on the right path.
 
-**The Docs Structure is dictated by [.vitepress/config.ts](https://github.com/mermaid-js/mermaid/blob/develop/packages/mermaid/src/docs/.vitepress/config.ts)**.
+## Technical Requirements and Setup
 
-**Note: Commits and Pull Requests should be directed to the develop branch.**
+### Technical Requirements
 
-## Branching
+These are the tools we use for working with the code and documentation.
 
-Mermaid uses a [Git Flow](https://guides.github.com/introduction/flow/)–inspired approach to branching. So development is done in the `develop` branch.
+- [volta](https://volta.sh/) to manage node versions.
+- [Node.js](https://nodejs.org/en/). `volta install node`
+- [pnpm](https://pnpm.io/) package manager. `volta install pnpm`
+- [npx](https://docs.npmjs.com/cli/v8/commands/npx) the packaged executor in npm. This is needed [to install pnpm.](#2-install-pnpm)
 
-Once development is done we branch a `release` branch from `develop` for testing.
+Follow [the setup steps below](#setup) to install them and verify they are working
 
-Once the release happens we merge the `release` branch with `master` and kill the `release` branch.
+### Setup
 
-This means that **you should branch off your pull request from develop** and direct all Pull Requests to it.
+Follow these steps to set up the environment you need to work on code and/or documentation.
+
+#### 1. Fork and clone the repository
+
+In GitHub, you first _fork_ a repository when you are going to make changes and submit pull requests.
+
+Then you _clone_ a copy to your local development machine (e.g. where you code) to make a copy with all the files to work with.
+
+[Here is a GitHub document that gives an overview of the process.](https://docs.github.com/en/get-started/quickstart/fork-a-repo)
+
+#### 2. Install pnpm
+
+Once you have cloned the repository onto your development machine, change into the `mermaid` project folder so that you can install `pnpm`. You will need `npx` to install pnpm because volta doesn't support it yet.
+
+Ex:
+
+```bash
+# Change into the mermaid directory (the top level director of the mermaid project repository)
+cd mermaid
+# npx is required for first install because volta does not support pnpm yet
+npx pnpm install
+```
+
+#### 3. Verify Everything Is Working
+
+Once you have installed pnpm, you can run the `test` script to verify that pnpm is working _and_ that the repository has been cloned correctly:
+
+```bash
+pnpm test
+```
+
+The `test` script and others are in the top-level `package.json` file.
+
+All tests should run successfully without any errors or failures. (You might see _lint_ or _formatting_ warnings; those are ok during this step.)
+
+### Docker
+
+If you are using docker and docker-compose, you have self-documented `run` bash script, which is a convenient alias for docker-compose commands:
+
+```bash
+./run install # npx pnpm install
+./run test # pnpm test
+```
 
 ## Contributing Code
 
-We make all changes via Pull Requests. As we have many Pull Requests from developers new to mermaid, we have put in place a process, wherein _knsv, Knut Sveidqvist_ is the primary reviewer of changes and merging pull requests. The process is as follows:
+The basic steps for contributing code are:
 
-- Large changes reviewed by knsv or other developer asked to review by knsv
-- Smaller, low-risk changes like dependencies, documentation, etc. can be merged by active collaborators
-- Documentation (we encourage updates to the `/packages/mermaid/src/docs` folder; you can submit them via direct commits)
+```mermaid
+graph LR
+    git[1. Checkout a  git branch] --> codeTest[2. Write tests and code] --> doc[3. Update documentation] --> submit[4. Submit a PR] --> review[5. Review and merge]
+```
 
-When you commit code, create a branch with the following naming convention:
+1. **Create** and checkout a git branch and work on your code in the branch
+2. Write and update **tests** (unit and perhaps even integration (e2e) tests) (If you do TDD/BDD, the order might be different.)
+3. **Let users know** that things have changed or been added in the documents! This is often overlooked, but _critical_
+4. **Submit** your code as a _pull request_.
+5. Maintainers will **review** your code. If there are no changes necessary, the PR will be merged. Otherwise, make the requested changes and repeat.
 
-Start with the type, such as **feature** or **bug**, followed by the issue number for reference, and a text that describes the issue.
+### 1. Checkout a git branch
 
-**One example:**
+Mermaid uses a [Git Flow](https://guides.github.com/introduction/flow/)–inspired approach to branching.
 
-`feature/945_state_diagrams`
+Development is done in the `develop` branch.
 
-**Another example:**
+Once development is done we create a `release/vX.X.X` branch from `develop` for testing.
 
-`bug/123_nasty_bug_branch`
+Once the release happens we add a tag to the `release` branch and merge it with `master`. The live product and on-line documentation are what is in the `master` branch.
 
-## Contributing to Documentation
+**All new work should be based on the `develop` branch.**
 
-If it is not in the documentation, it's like it never happened. Wouldn't that be sad? With all the effort that was put into the feature?
+**When you are ready to do work, always, ALWAYS:**

-## How to Contribute to Documentation
+- The first part is the **type** of change: a feature, bug, chore, or documentation change ('docs')
+- followed by a _slash_ (which helps to group like types together in many git tools)
+- followed by the **issue number**
+- followed by an _underscore_ ('\_')
+- followed by a short text description (but use dashes ('-') or underscores ('\_') instead of spaces)
 
-We are a little less strict here, it is OK to commit directly in the `develop` branch if you are a collaborator.
+If your work is specific to a single diagram type, it is a good idea to put the diagram type at the start of the description. This will help us keep release notes organized: it will help us keep changes for a diagram type together.
 
-The documentation is located in the `src/docs` directory and organized according to relevant subfolder.
+**Ex: A new feature described in issue 2945 that adds a new arrow type called 'florbs' to state diagrams**
 
-The `docs` folder will be automatically generated when committing to `src/docs` and should not be edited manually.
+`feature/2945_state-diagram-new-arrow-florbs`
 
-We encourage contributions to the documentation at [mermaid-js/mermaid/src/docs](https://github.com/mermaid-js/mermaid/tree/develop/packages/mermaid/src/docs). We publish documentation using GitHub Pages with [Docsify](https://www.youtube.com/watch?v=TV88lp7egMw&t=3s)

-### Add Unit Tests for Parsing
+### 2. Write Tests
 
-This is important so that, if someone that does not know about this great feature suggests a change to the grammar, they get notified early on when that change breaks the parser. Another important aspect is that, without proper parsing, tests refactoring is pretty much impossible.
+Tests ensure that each function, module, or part of code does what it says it will do. This is critically
+important when other changes are made to ensure that existing code is not broken (no regression).
 
-### Add E2E Tests
+Just as important, the tests act as _specifications:_ they specify what the code does (or should do).
+Whenever someone is new to a section of code, they should be able to read the tests to get a thorough understanding of what it does and why.
 
-This tests the rendering and visual appearance of the diagrams. This ensures that the rendering of that feature in the e2e will be reviewed in the release process going forward. Less chance that it breaks!
+If you are fixing a bug, you should add tests to ensure that your code has actually fixed the bug, to specify/describe what the code is doing, and to ensure the bug doesn't happen again.
+(If there had been a test for the situation, the bug never would have happened in the first place.)
+You may need to change existing tests if they were inaccurate.
+
+If you are adding a feature, you will definitely need to add tests. Depending on the size of your feature, you may need to add integration tests.
+
+#### Unit Tests
+
+Unit tests are tests that test a single function or module. They are the easiest to write and the fastest to run.
+
+Unit tests are mandatory all code except the renderers. (The renderers are tested with integration tests.)
+
+We use [Vitest](https://vitest.dev) to run unit tests.
+
+You can use the following command to run the unit tests:
+
+```sh
+pnpm test
+```
+
+When writing new tests, it's easier to have the tests automatically run as you make changes. You can do this by running the following command:
+
+```sh
+pnpm test:watch
+```
+
+#### Integration/End-to-End (e2e) tests
+
+These test the rendering and visual appearance of the diagrams.
+This ensures that the rendering of that feature in the e2e will be reviewed in the release process going forward. Less chance that it breaks!
 
 To start working with the e2e tests:
 
-1. Run `pnpm run dev` to start the dev server
-2. Start **Cypress** by running `pnpm exec cypress open` in the **mermaid** folder.
+1. Run `pnpm dev` to start the dev server

-### How to Contribute a Suggestion
+### 3. Update Documentation
+
+If the users have no way to know that things have changed, then you haven't really _fixed_ anything for the users; you've just added to making Mermaid feel broken.
+Likewise, if users don't know that there is a new feature that you've implemented, it will forever remain unknown and unused.
+
+The documentation has to be updated to users know that things have changed and added!
+
+We know it can sometimes be hard to code _and_ write user documentation.
+
+Our documentation is managed in `packages/mermaid/src/docs`. Details on how to edit is in the [Contributing Documentation](#contributing-documentation) section.
+
+Create another issue specifically for the documentation.  
+You will need to help with the PR, but definitely ask for help if you feel stuck.
+When it feels hard to write stuff out, explaining it to someone and having that person ask you clarifying questions can often be 80% of the work!
+
+When in doubt, write up and submit what you can. It can be clarified and refined later. (With documentation, something is better than nothing!)
+
+### 4. Submit your pull request
+
+**[TODO - PR titles should start with (fix | feat | ....)]**
+
+We make all changes via Pull Requests (PRs). As we have many Pull Requests from developers new to Mermaid, we have put in place a process wherein _knsv, Knut Sveidqvist_ is in charge of the final release process and the active maintainers are in charge of reviewing and merging most PRs.
+
+- PRs will be reviewed by active maintainers, who will provide feedback and request changes as needed.
+- The maintainers will request a review from knsv, if necessary.
+- Once the PR is approved, the maintainers will merge the PR into the `develop` branch.
+- When a release is ready, the `release/x.x.x` branch will be created, extensively tested and knsv will be in charge of the release process.
+
+**Reminder: Pull Requests should be submitted to the develop branch.**
