# Contribution guide

First, thank you for contributing! We love and encourage pull requests from
everyone. Please follow the guidelines:

- Check the open [issues](https://git.frostfs.info/TrueCloudLab/frostfs-node/issues) and
  [pull requests](https://git.frostfs.info/TrueCloudLab/frostfs-node/pulls) for existing
  discussions.

- Open an issue first, to discuss a new feature or enhancement.

- Write tests, and make sure the test suite passes locally and on CI.

- Open a pull request, and reference the relevant issue(s).

- Make sure your commits are logically separated and have good comments
  explaining the details of your change.

- After receiving feedback, amend your commits or add new ones as
  appropriate.

- **Have fun!**

## Development Workflow

Start by forking the `frostfs-node` repository, make changes in a branch and then
send a pull request. We encourage pull requests to discuss code changes. Here
are the steps in details:

### Set up your Forgejo repository
Fork [FrostFS node upstream](https://git.frostfs.info/TrueCloudLab/frostfs-node) source
repository to your own personal repository. Copy the URL of your fork (you will
need it for the `git clone` command below).

```sh
$ git clone https://git.frostfs.info/TrueCloudLab/frostfs-node
```

### Set up git remote as ``upstream``
```sh
$ cd frostfs-node
$ git remote add upstream https://git.frostfs.info/TrueCloudLab/frostfs-node
$ git fetch upstream
$ git merge upstream/master
...
```

### Create your feature branch
Before making code changes, make sure you create a separate branch for these
changes. Maybe you will find it convenient to name branch in
`<type>/<Issue>-<changes_topic>` format.

```
$ git checkout -b feature/123-something_awesome
```

### Test your changes
After your code changes, make sure

- To add test cases for the new code.
- To run `make lint` and `make staticcheck-run`
- To squash your commits into a single commit or a series of logically separated
  commits run `git rebase -i`. It's okay to force update your pull request.
- To run `make test` and `make all` completes.

### Commit changes
After verification, commit your changes. This is a [great
post](https://chris.beams.io/posts/git-commit/) on how to write useful commit
messages. Try following this template:

```
[#Issue] <component> Summary

Description

<Macros>

<Sign-Off>
```

```
$ git commit -sam '[#123] Add some feature'
```

### Push to the branch
Push your locally committed changes to the remote origin (your fork)
```
$ git push origin feature/123-something_awesome
```

### Create a Pull Request
Pull requests can be created via Forgejo. Refer to [this
document](https://docs.codeberg.org/collaborating/pull-requests-and-git-flow/) for
detailed steps on how to create a pull request. After a Pull Request gets peer
reviewed and approved, it will be merged.

## DCO Sign off

All authors to the project retain copyright to their work. However, to ensure
