§ Contribution Guide
We welcome and encourage community contributions to Flynn.
Please familiarize yourself with the Contribution Guidelines and Project Roadmap before contributing.
There are many ways to help Flynn besides contributing code:
- Fix bugs or file issues
- Improve the documentation
§ Contributing Code
Unless you are fixing a known bug, we strongly recommend discussing it with the core team via a GitHub issue, IRC, or email before getting started to ensure your work is consistent with Flynn’s roadmap and architecture.
All contributions are made via pull request. Note that all patches from all contributors get reviewed. After a pull request is made other contributors will offer feedback, and if the patch passes review a maintainer will accept it with a comment. When pull requests fail testing, authors are expected to update their pull requests to address the failures until the tests pass and the pull request merges successfully.
At least one review from a maintainer is required for all patches (even patches from maintainers).
Reviewers should leave a “LGTM” comment once they are satisfied with the patch. If the patch was submitted by a maintainer with write access, the pull request should be merged by the submitter after review.
§ Code Style
Please follow these guidelines when formatting source code:
- Go code should match the output of
- Shell scripts should adhere to the Google Shell Style guide

§ Pull request procedure
To make a pull request, you will need a GitHub account; if you are unclear on this process, see GitHub’s documentation on forking and pull requests. Pull requests should be targeted at the
master branch. Before creating a pull request, go through this checklist:
- Create a feature branch off of
masterso that changes do not get mixed up.
- Rebase your local changes against the
- Run the full project test suite with the
go test ./...(or equivalent) command and confirm that it passes.
gofmt -s(if the project is written in Go).
- Accept the Developer’s Certificate of Origin on all commits (see above).
- Ensure that each commit has a subsystem prefix (ex:
Pull requests will be treated as “review requests,” and maintainers will give feedback on the style and substance of the patch.
Normally, all pull requests must include tests that test your change. Occasionally, a change will be very difficult to test for. In those cases, please include a note in your commit message explaining why.
