* If you aren't sure, you can ask on the [**IRC channel**](https://webchat.freenode.net/?channels=qtox) or read our [**wiki**](https://github.com/tux3/qTox/wiki) first.
* **Screenshots**! A screenshot is worth a thousand words. Just upload it. [(How?)](https://help.github.com/articles/file-attachments-on-issues-and-pull-requests)
* If your commit fixes a reported issue (for example #4134), add the following message to the commit `Fixes #4134.`. [Here is an example](https://github.com/tux3/qTox/commit/87160526d5bafcee7869d6741a06045e13d731d5).
* **Search** the pull request history! Others might have already implemented your idea and it could be waiting to be merged (or have been rejected already). Save your precious time by doing a search first.
* When resolving merge conflicts, do `git rebase <target_branch_name>`, don't do `git pull`. Then you can start fixing the conflicts. [Here is a good explanation](https://www.atlassian.com/git/tutorials/merging-vs-rebasing).
We have very precise rules over how our git commit messages can be formatted.
This leads to **more readable messages** that are easy to follow when looking
through the **project history**. But also, we use the git commit messages to
**generate the qTox change log** using [clog-cli]
(https://github.com/clog-tool/clog-cli).
### Commit Message Format
Each commit message consists of a **header**, a **body** and a **footer**. The header has a special
format that includes a **type**, a **scope** and a **subject**:
```
<type>(<scope>): <subject>
<BLANKLINE>
<body>
<BLANKLINE>
<footer>
```
The **header** is mandatory and the **scope** of the header is optional.
Any line of the commit message cannot be longer 100 characters! This allows the message to be easier
to read on GitHub as well as in various git tools.
Note that in the future `gitcop` will be used to check if commits in pull
request conform to commit message format, but since it can't be configured to
have an optional `(<scope>)`, it will claim that messages without it are wrong,
while they're perfectly fine.
### Revert
If the commit reverts a previous commit, it should begin with `revert: `, followed by the header of the reverted commit. In the body it should say: `This reverts commit <hash>.`, where the hash is the SHA of the commit being reverted.
### Type
Must be one of the following:
* **feat**: A new feature
* **fix**: A bug fix
* **docs**: Documentation only changes
* **style**: Changes that do not affect the meaning of the code (white-space, formatting, etc)
* **refactor**: A code change that neither fixes a bug nor adds a feature
* **perf**: A code change that improves performance
* **test**: Adding missing tests
* **chore**: Changes to the build process or auxiliary tools and libraries such as documentation
generation
### Scope
The scope could be anything specifying place of the commit change. For example `$location`,
