+# Contributing
+
+So you want to help? That's great!
+
+![Happy people jumping with excitement](https://media.giphy.com/media/BlVnrxJgTGsUw/giphy.gif)
+
+Here are a few things to know to get you started on the right path.
+
+## Development Installation
+
+```bash
+git clone git@github.com:mermaid-js/mermaid.git
+cd mermaid
+yarn
+yarn test
+```
+
+## Committing code
+
+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 /src/docs
+
+The source files for the project documentation are located in the `/src/docs` directory. This is where you should make changes.
+The files under `/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 /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"]
+
+```
+
+**_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 `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 source files for documentation are in `/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.

-## Special note regarding version 8.2
+<img src="./img/header.png" alt="" />
 
-In version 8.2 a security improvement was introduced. A securityLevel configuration was introduced which sets the level of trust to be used on the parsed diagrams.
+:trophy: **Mermaid was nominated and won the [JS Open Source Awards (2019)](https://osawards.com/javascript/2019) in the category "The most exciting use of technology"!!!**
 
-* **`strict`**: (default) tags in text are encoded, click functionality is disabled
-* `loose`: tags in text are allowed, click functionality is enabledClosed issues:
+**Thanks to all involved, people committing pull requests, people answering questions! 🙏**
 
-⚠️ **Note** : This changes the default behaviour of mermaid so that after upgrade to 8.2, if the securityLevel is not configured, tags in flowcharts are encoded as tags and clicking is prohibited.

The first official book on Mermaid is available for purchase. Check it out!"></a>
 
-If your application is taking resposibility for the diagram source security you can set the securityLevel accordingly. By doing this clicks and tags are again allowed.

+<!-- <Main description>   -->
 
-**🖖 Keep a steady pulse: mermaid needs more Collaborators [#866](https://github.com/knsv/mermaid/issues/866)**
+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.
 
-![banner](./img/header.png)
+> Doc-Rot is a Catch-22 that Mermaid helps to solve.
 
-Generation of diagrams and flowcharts from text in a similar manner as markdown.
+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/>
 
-Ever wanted to simplify documentation and avoid heavy tools like Visio when explaining your code?
+Mermaid allows even non-programmers to easily create detailed diagrams through the [Mermaid Live Editor](https://mermaid.live/).<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).
 
-This is why mermaid was born, a simple markdown-like script language for generating charts from text via javascript.
+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).
 
-**Mermaid was nomiated and won the JS Open Source Awards (2019) in the category _The most exciting use of technology_!!! Thanks to all involved, people committing pull requests, people answering questions and special thanks to Tyler Long who is helping me maintain the project.**
+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
 
-Here is the full list of the projects [contributors](https://github.com/knsv/mermaid/graphs/contributors).
+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.
+
+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.
+
+_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._
+
+## 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.live/) 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)。
+
+关于如何贡献的详细信息可以在 [贡献指南](CONTRIBUTING.md) 中找到。
+
+## 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）。
