# How to Contribute

We'd love to receive your patches and contributions. Please keep your PRs as draft until such time that you would like us to review them.

## Code Reviews

All submissions, including submissions by project members, require review. We use GitHub pull requests for this purpose. Consult
[GitHub Help](https://help.github.com/articles/about-pull-requests/) for more information on using pull requests.

## Pipeline

Ensure you run the linter prior to submitting your pull request and the CI-CD pipeline is green before removing the draft designation.

```bash
./cosmos1/scripts/format.sh
```

## Signing Your Work

* We require that all contributors "sign-off" on their commits. This certifies that the contribution is your original work, or you have rights to submit it under the same license, or a compatible license.

  * Any contribution which contains commits that are not Signed-Off will not be accepted.

* To sign off on a commit you simply use the `--signoff` (or `-s`) option when committing your changes:
  ```bash
  $ git commit -s -m "Add cool feature."
  ```
  This will append the following to your commit message:
  ```
  Signed-off-by: Your Name <your@email.com>
  ```
