To help your project contributors do good work, you can add a file with contribution guidelines to your project repository's root,
.github folder. Then, whenever someone opens a pull request or creates an issue, they will see a link to that file.
For the repository owner, contribution guidelines are a way to communicate how people should contribute.
For contributors, the guidelines help them verify that they're submitting well-formed pull requests and opening useful issues.
For both owners and contributors, contribution guidelines save time and hassle caused by improperly created pull requests or issues that have to be rejected and re-submitted.
Tip: Repository maintainers can set specific guidelines for issues by creating an issue or pull request template for the repository. For more information, see "About issue and pull request templates."
Adding a CONTRIBUTING file
On GitHub, navigate to the main page of the repository.
Above the file list, click Create new file.
Decide whether to store your contributing guidelines in your repository's root,
.githubdirectory. Then, in the filename field, type the name and extension for the file. Contributing guidelines filenames are not case sensitive, and can have an extension such as .md or .txt.
- To make your contributing guidelines visible in the repository's root directory, type CONTRIBUTING.
- To make your contributing guidelines visible in the repository's
docsdirectory, type docs/ to create the new directory, then CONTRIBUTING.
- In the new file, add contribution guidelines. These could include:
- Steps for creating good issues or pull requests.
- Links to external documentation, mailing lists, or a code of conduct.
- Community and behavioral expectations.
At the bottom of the page, type a short, meaningful commit message that describes the change you made to the file. You can attribute the commit to more than one author in the commit message. For more information, see "Creating a commit with multiple co-authors."
Below the commit message fields, decide whether to add your commit to the current branch or to a new branch. If your current branch is
master, you should choose to create a new branch for your commit and then create a pull request.
Click Propose new file.
