# Contribution Guidelines
Thank you for your interest in contributing to the documentation! You will be helping the open source community and other developers interested in learning more about Medusa and using it.
:::tip
This guide is specific to contributing to the documentation. If youre interested in contributing to Medusas codebase, check out the [contributing guidelines in the Medusa GitHub repository](https://github.com/medusajs/medusa/blob/master/CONTRIBUTING.md).
:::
## Site Setup
The documentation website is built with [Docusaurus](https://docusaurus.io/), a framework that optimizes documentation creation. If youre not familiar with Docusaurus, its recommended to check out the [Installation documentation](https://docusaurus.io/docs/installation) on their website to better understand Docusaurus, how it works, its structure, and more details.
The documentation codebase is hosted as part of the [medusa repository](https://github.com/medusajs/medusa) on GitHub. Youll find the code that runs the docusaurus website under the [www/docs](https://github.com/medusajs/medusa/tree/master/www/docs) directory.
## Documentation Content
The documentation content is written in Markdown format and is located in the [docs/content](https://github.com/medusajs/medusa/tree/master/docs/content) directory of the same repository. If youre not familiar with Markdown, check out [this cheat sheet](https://www.markdownguide.org/cheat-sheet/) for a quick start.
Youll also find MDX files. MDX files combine the power of Markdown with React. So, the content of the file can contain JSX components and import statements, among other features. You can learn more about [MDX in docusauruss guide.](https://docusaurus.io/docs/markdown-features/react)
## What You Can Contribute To
- You can contribute to the Docusaurus codebase to add a new feature or fix a bug in the documentation website.
- You can contribute to the documentation content either by fixing errors you find or adding documentation pages.
## What You Cant Contribute To
The [Services Reference](/references/services/classes/AuthService) is an automatically generated API reference using Typedoc. So, you cant contribute to it by making changes to its markdown files.
You can, however, contribute to the script generating it if you find any issues in it.
## Style Guide
When you contribute to the documentation content, make sure to follow the [documentation style guide](https://www.notion.so/Style-Guide-Docs-fad86dd1c5f84b48b145e959f36628e0).
## How to Contribute
If youre fixing errors in an existing documentation page, you can scroll down to the end of the page and click on the “Edit this page” link. Youll be redirected to the GitHub edit form of that page and you can make edits directly and submit a pull request (PR).
If youre adding a new page or contributing to the codebase, fork the repository, create a new branch, and make all changes necessary in your repository. Then, once youre done creating a PR in the Medusa repository.
For more details on how to contribute, check out [the contribution guidelines in the Medusa repository](https://github.com/medusajs/medusa/blob/master/CONTRIBUTING.md).
### Branch Name
When you make edit to an existing documentation page or fork the repository to make changes to the documentation, you have to create a new branch.
Make sure that the branch name starts with `docs/`. For example, `docs/fix-services`.
### Pull Request Conventions
When you create a pull request, prefix the title with “docs:”. Make sure to keep “docs” in small letters.
<!-- vale off -->
In the body of the PR, explain clearly what the PR does. If the PR solves an issue, use [closing keywords](https://docs.github.com/en/issues/tracking-your-work-with-issues/linking-a-pull-request-to-an-issue#linking-a-pull-request-to-an-issue-using-a-keyword) with the issue number. For example, “Closes #1333”.
<!-- vale on -->
## Sidebar
When you add a new page to the documentation, you must add the new page in `www/docs/sidebars.js` under the `docsSidebar`. You can learn more about the syntax used [here](https://docusaurus.io/docs/sidebar/items).
### Terminology
When the documentation page is a conceptual or overview documentation, the label in the sidebar should start with a noun.
When the documentation page is a tutorial documentation, the label in the sidebar should start with a verb. An exception of this rule are integration documentations and upgrade guides.
### Character Count
The character count of the sidebar item's label must be at most twenty seven characters. For the API Reference, the sidebar item's label must be at most twenty five characters.
## Notes and Additional Information
When displaying notes and additional information in a documentation page, use [Admonitions](https://docusaurus.io/docs/markdown-features/admonitions). Make sure the type of admonition used matches the notes importance to the current document.
If the note is something developers have to be careful of doing or not doing, use the `caution` or `danger` admonitions based on how critical it is.
If the note is defining something to the developer in case theyre not familiar with it, use the `info` admonition.
If the note displays helpful information and tips use the `tip` admonition.
If the admonition does not match any of the mentioned criteria, always default to the `note` admonition.
## Images
If you are adding images to a documentation page, you can host the image on [Imgur](https://imgur.com) for free.
## NPM and Yarn Code Blocks
If youre adding code blocks that use NPM and Yarn, you must use the [npm2yarn syntax](https://docusaurus.io/docs/markdown-features/code-blocks#npm2yarn-remark-plugin).
For example:
~~~md
```bash npm2yarn
npm run start
```
~~~
The code snippet must be written using NPM, and the `npm2yarn` plugin will automatically transform it to Yarn.
### Expand Commands
<!-- vale off -->
Don't use commands in their abbrivated terms. For example, instead of `npm i` use `npm install`.
<!-- vale on -->
### Run Command
Make sure to always use the `run` command when the command runs a script.
<!-- vale off -->
For example, even though you can run the `start` script using NPM with `npm start`, however, to make sure its transformed properly to a Yarn command, you must add the `run` keyword before `start`.
<!-- vale on -->
### Global Option
When a command uses the global option `-g`, add it at the end of the NPM command to ensure that its transformed to a Yarn command properly. For example:
```bash npm2yarn
npm install @medusajs/medusa-cli -g
```
## Linting with Vale
Medusa uses Vale to lint documentation pages and perform checks on incoming PRs into the repository.
### Result of PR Checks
You can check the result of running the "lint" action on your PR by clicking the Details link next to it. You can find there all errors that you need to fix.
### Run Vale Locally
If you want to check your work locally, you can do that by:
1. [Installing Vale](https://vale.sh/docs/vale-cli/installation/) on your machine.
2. Change to the `docs` directory:
```bash
cd docs
```
3\. Run the `run-vale` script:
```bash
./run-vale.sh error
```
### VS Code Extension
To facilitate writing documentation, you can optionally use the [Vale VS Code extension](https://github.com/errata-ai/vale-vscode). This will show you any errors in your documentation while writing it.
### Linter Exceptions
If it's needed to break some style guide rules in a document, you can wrap the parts that the linter shouldn't scan with the following comments in the `md` or `mdx` files:
```md
<!-- vale off -->
content that shouldn't be scanned for errors here...
<!-- vale on -->
```
You can also disable specific rules. For example:
```md
<!-- vale docs.Numbers = NO -->
Medusa supports Node versions 14 and 16.
<!-- vale docs.Numbers = YES -->
```
If you use this in your PR, you must justify its usage.
## Need Additional Help
If you need any additional help while contributing, you can join Medusa's [Discord server](https://discord.gg/medusajs) and ask Medusas core team as well as the community any questions.
