+### Mermaid is ESM only!
+
+We've dropped CJS support. So, you will have to update your import scripts as follows.
+
+```html
+<script type="module">
+  import mermaid from 'https://cdn.jsdelivr.net/npm/mermaid@10/dist/mermaid.esm.min.mjs';
+  mermaid.initialize({ startOnLoad: true });
+</script>
+```
+
+You can keep using v9 by adding the `@9` in the CDN URL.
+
+```diff
+- <script src="https://cdn.jsdelivr.net/npm/mermaid/dist/mermaid.js"></script>
++ <script src="https://cdn.jsdelivr.net/npm/mermaid@9/dist/mermaid.js"></script>
+```
+
+### mermaid.render is async and doesn't accept callbacks
+
+```js
+// < v10
+mermaid.render('id', 'graph TD;\nA-->B', (svg, bindFunctions) => {
+  element.innerHTML = svg;
+  if (bindFunctions) {
+    bindFunctions(element);

+### Init deprecated and InitThrowsErrors removed
+
+The config passed to `init` was not being used eariler.
+It will now be used.
+The `init` function is deprecated and will be removed in the next major release.
+init currently works as a wrapper to `initialize` and `run`.
+
+```js
+// < v10
+mermaid.init(config, selector, cb);
+
+//>= v10
+mermaid.initialize(config);
+mermaid.run({
+  querySelector: selector,
+  postRenderCallback: cb,

+mermaid.run({
+  querySelector: selector,
+  postRenderCallback: cb,
+  suppressErrors: false,
+});
+```
+
+// TODO: Populate changelog pre v10
 
 - Config has a lot of changes
 - globalReset resets to `defaultConfig` instead of current config. Use `reset` instead.

@@ -18,148 +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 `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.
-
-```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
 ```
 
+## Testing
+
+```bash
+# Run unit test
+pnpm test
+# Run unit test in watch mode
+pnpm test:watch
+# Run E2E test
+pnpm e2e
+# Debug E2E tests
+pnpm dev
+pnpm cypress:open # in another terminal
+```
+
+## Branch name format:
+
+```text
+   [feature | bug | chore | docs]/[issue number]_[short description using dashes ('-') or underscores ('_') instead of spaces]
+```
+
+eg: `feature/2945_state-diagram-new-arrow-florbs`, `bug/1123_fix_random_ugly_red_text`
+
+## 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 [Docsify](https://docsify.js.org), a simple documentation site generator.**
-
-If you want to preview the whole documentation site on your machine, you need to install `docsify-cli`:
-
-```sh
-$ npm i docsify-cli -g
-```
-
-If you are more familiar with Yarn, you can use the following command:
-
-```sh
-$ yarn global add docsify-cli
-```
-
-The above command will install `docsify-cli` globally.
-If the installation is successful, the command `docsify` will be available in your `PATH`.
-
-You can now run the following command to serve the documentation site:
-
-```sh
-$ docsify serve docs
-```
-
-Once the local HTTP server is listening, you can point your browser at http://localhost:3000.
-
-## 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 `src/docs/_sidebar.md`.
-
-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.

-# Whoa, what's going on here?
+<br>
+<br>
 
-We are transforming the Mermaid repository to a so called mono-repo. This is a part of the effort to decouple the diagrams from the core of mermaid. This will:
-
-- Make it possible to select which diagrams to include on your site
-- Open up for lazy loading
-- Make it possible to add diagrams from outside of the Mermaid repository
-- Separate the release flow between different diagrams and the Mermaid core
-
-As such be aware of some changes..
-
-# We use pnpm now
-
-# The source code has moved
-
-It is now located in the src folder for each respective package located as subfolders in packages.
