-# How to contribute
+# Contributing
 
-Great that you want to be involved in this project! Contributing is fun and contributions are GREAT! :)
+So you want to help? That's great!
 
-This page is currently a starting point and is not so rigorous to start with.
+![Happy people jumping with excitement](https://media.giphy.com/media/BlVnrxJgTGsUw/giphy.gif)
 
-Some important guidlines:
+Here are a few things to know to get you started on the right path.
 
-* The work will be organized using the issues list
-    * In the list there will be the bugs/enhancements etc we are working with in the project
-    * There will be milestones outlineing the roadmap ahead
-    * There will issues marked with help wanted
+## Committing code
 
-The issue list and the items marked with **help wanted** is a good starting point if you want to do some work.
+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 docs folder is also allowed via direct commits)
 
-## Guidelines for avoiding duplicate work
+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.
 
-Contributing is great. It is not so fun when you are done with your issue and just before you're about to push your
-change you can't because someone else just pushed the same fix so you have wasted your time. The guidelines below are in
-place to prevent this:
+One example:
 
-* Comment in the issue that you are working on it. You will then be added as an assignee (eventually).
-* When you pick an issue to work on.
-    * Check that the issue not assigned
-    * Also check the comments so that no one has started working on it before beeing officially assigned.
+`feature/945_state_diagrams`
 
+Another:
 
-## Submitting changes
+`bug/123_nasty_bug_branch`
 
-Please send a GitHub Pull Request with a clear list of what you've done (read more about pull requests). When you send
-a pull request, we will love you forever if you include jasmine tests. We can always use more test coverage.
+## Committing documentation
 
-Always write a clear log message for your commits. One-line messages are fine for small changes, but bigger changes should look like this:
+Less strict here, it is OK to commit directly in the `develop` branch if you are a collaborator.
 
-$ git commit -m "A brief summary of the commit
->
-> A paragraph describing what changed and its impact."
-Coding conventions
-Start reading our code and you'll get the hang of it. We optimize for readability:
+The documentation is located in the `docs` directory and published using GitHub Pages.
+The documentation site is powered by [Docsify](https://docsify.js.org), a simple documentation site generator.
 
-This is open source software. Consider the people who will read your code, and make it look nice for them. It's sort of
-like driving a car: Perhaps you love doing donuts when you're alone, but with passengers the goal is to make the ride as
-smooth as possible.
+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).
 
-So that we can consistently serve images from the CDN, always use image_path or image_tag when referring to images.
-Never prepend "/images/" when using image_path or image_tag.
-Also for the CDN, always use cwd-relative paths rather than root-relative paths in image URLs in any CSS. So instead of
-url('/images/blah.gif'), use url('../images/blah.gif').
+If you want to preview the documentation site on your machine, you need to install `docsify-cli`:
 
-# Build instructions
-
-Fork, then:
-
-```
-yarn install
+```sh
+$ npm i docsify-cli -g
 ```
 
-Then the dependencies will have been installed. You use gulp and yarn calls as build tools.
+If you are more familiar with Yarn, you can use the following command:
 
-The following targets are probably interesting:
-
-* jison - compiles the jison grammars to parser files
-
-for instance:
-```
-gulp jison
+```sh
+$ yarn global add docsify-cli
 ```
 
-To build:
+The above command will install `docsify-cli` globally.
+If the installation is successful, the command `docsify` will be available in your `PATH`.
 
-```
-yarn build
+You can now run the following command to serve the documentation site:
+
+```sh
+$ docsify serve docs
 ```
 
-To run the tests:
+Once the local HTTP server is listening, you can point your browser at http://localhost:3000.
 
-```
-yarn test
-```
+## Branching
 
-Make sure you have Chrome browser installed. We use Chrome headless for testing.
+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.
 
-Manual test:
+Once development is done we branch a release branch from develop for testing.
 
-```
-open dist/demo/index.html
-```
+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 `yarn dev` to start the dev server, after that start cypress by running `cypress open` in the mermaid folder. (Make sure you have path to cypress in order, the binary is located in node_modules/.bin).
+
+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 docs are located in the docs folder and are ofc written in markdown. Just pick the right section and start typing. If you want to add to the structure as in adding a new section and new file you do that via the _navbar.md.
+
+The changes in master is reflected in http://mermaid-js.github.io/mermaid/ once released the updates are committed to https://mermaid-js.github.io/#/
+
+## 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.

+## About
+
+<!-- <Main description>   -->
+Mermaid is a Javascript based diagramming and charting tool that uses Markdown-inspired text definitions and a renderer to create and modify complex diagrams.  The main purpose of Mermaid is to help documentation catch up with development.
+
+> Doc-Rot is a Catch-22 that Mermaid helps to solve.
+
+Diagramming and documentation costs precious developer time and gets outdated quickly.
+But not having diagrams or docs ruins productivity and hurts organizational learning.<br/>
+Mermaid addresses this problem by enabling users to create easily modifiable diagrams, it can also be made part of production scripts (and other pieces of code).<br/>
+ <br/>
+
+Mermaid allows even non-programmers to easily create detailed diagrams through the [Mermaid Live Editor](https://mermaid-js.github.io/mermaid-live-editor/).<br/>
+[Tutorials](./docs/Tutorials.md) has video tutorials.
+Use Mermaid with your favorite applications, check out the list of [Integrations and Usages of Mermaid](./docs/integrations.md).
+
+You can also use Mermaid within [GitHub](https://github.blog/2022-02-14-include-diagrams-markdown-files-mermaid/) as well many of your other favorite applications, check out the list of [Integrations and Usages of Mermaid](./docs/integrations.md).
+
+For a more detailed introduction to Mermaid and some of its more basic uses, look to the [Beginner's Guide](./docs/n00b-overview.md), [Usage](./docs/usage.md) and [Tutorials](./docs/Tutorials.md).

+## Security and safe diagrams
 
+For public sites, it can be precarious to retrieve text from users on the internet, storing that content for presentation in a browser at a later stage. The reason is that the user content can contain embedded malicious scripts that will run when the data is presented. For Mermaid this is a risk, specially as mermaid diagrams contain many characters that are used in html which makes the standard sanitation unusable as it also breaks the diagrams. We still make an effort to sanitise the incoming code and keep refining the process but  it is hard to guarantee that there are no loop holes.
 
-## Lint
+As an extra level of security for sites with external users we are happy to introduce a new security level in which the diagram is rendered in a sandboxed iframe preventing javascript in the code from  being executed. This is a great step forward for better security.
 
-    yarn lint
+*Unfortunately you can not have a cake and eat it at the same time which in this case means that some of the interactive functionality gets blocked along with the possible malicious code.*
 
-We use [JavaScript Standard Style](https://github.com/feross/standard).
-We recommend you installing [editor plugins](https://github.com/feross/standard#are-there-text-editor-plugins) so you can get real time lint result.
+## Reporting vulnerabilities
+To report a vulnerability, please e-mail security@mermaid.live with a description of the issue, the steps you took to create the issue, affected versions, and if known, mitigations for the issue.

+## 关于 Mermaid
+
+<!-- <Main description>   -->
+Mermaid 是一个基于 Javascript 的图表绘制工具，通过解析类 Markdown 的文本语法来实现图表的创建和动态修改。Mermaid 诞生的主要目的是让文档的更新能够及时跟上开发进度。
+
+> Doc-Rot 是 Mermaid 致力于解决的一个难题。
+
+绘图和编写文档花费了开发者宝贵的开发时间，而且随着业务的变更，它很快就会过期。 但是如果缺少了图表或文档，对于生产力和团队新人的业务学习都会产生巨大的阻碍。 <br/>
+Mermaid 通过允许用户创建便于修改的图表来解决这一难题，它也可以作为生产脚本（或其他代码）的一部分。<br/>
+<br/>
+Mermaid 甚至能让非程序员也能通过 [Mermaid Live Editor](https://mermaid-js.github.io/mermaid-live-editor/) 轻松创建详细的图表。<br/>
+你可以访问 [教程](./docs/Tutorials.md) 来查看 Live Editor 的视频教程，也可以查看 [Mermaid 的集成和使用](./docs/integrations.md) 这个清单来检查你的文档工具是否已经集成了 Mermaid 支持。
+
+如果想要查看关于 Mermaid 更详细的介绍及基础使用方式，可以查看 [入门指引](./docs/n00b-overview.md), [用法](./docs/usage.md) 和 [教程](./docs/Tutorials.md).

+Mermaid 是一个不断发展中的社区，并且还在接收新的贡献者。有很多不同的方式可以参与进来，而且我们还在寻找额外的帮助。如果你想知道如何开始贡献，请查看 [这个 issue](https://github.com/mermaid-js/mermaid/issues/866)。

+
+## 安全
+
+对于公开网站来说，从互联网上的用户处检索文本、存储供后续在浏览器中展示的内容可能是不安全的，理由是用户的内容可能嵌入一些数据加载完成之后就会运行的恶意脚本，这些对于 Mermaid 来说毫无疑问是一个风险，尤其是 mermaid 图表还包含了许多在 html 中使用的字符，这意味着我们难以使用常规的手段来过滤不安全代码，因为这些常规手段会造成图表损坏。我们仍然在努力对获取到的代码进行安全过滤并不断完善我们的程序，但很难保证没有漏洞。
+
+作为拥有外部用户的网站的额外安全级别，我们很高兴推出一个新的安全级别，其中的图表在沙盒 iframe 中渲染，防止代码中的 javascript 被执行，这是在安全性方面迈出的一大步。
+
+*很不幸的是，鱼与熊掌不可兼得，在这个场景下它意味着在可能的恶意代码被阻止时，也会损失部分交互能力*。
+
+## 报告漏洞
+
+如果想要报告漏洞，请发送邮件到 security@mermaid.live, 并附上问题的描述、复现问题的步骤、受影响的版本，以及解决问题的方案（如果有的话）。
