# Contributing to Feign
Please read [HACKING](./HACKING.md) prior to raising change.

If you would like to contribute code you can do so through GitHub by forking the repository and sending a pull request (on a branch other than `master` or `gh-pages`).

## Pull Requests
Pull requests eventually need to resolve to a single commit. The commit log should be easy to read as a change log. We use the following form to accomplish that.
* First line is a <=72 character description in present tense, explaining what this does.
  * Ex. "Fixes regression on encoding vnd headers" > "Fixed encoding bug", which forces the reader to look at code to understand impact.
* Do not include issue links in the first line as that makes pull requests look weird.
  * Ex. "Addresses #345" becomes a pull request title: "Addresses #345 #346"
* After the first line, use markdown to concisely summarize the implementation.
  * This isn't in leiu of comments, and it assumes the reader isn't intimately familar with code structure.
* If the change closes an issue, note that at the end of the commit description ex. "Fixes #345"
  * GitHub will automatically close change with this syntax.
* If the change is notable, also update the [change log](./CHANGELOG.md) with your summary description.
  * The unreleased minor version is often a good default.

## Code Style

When submitting code, please use the feign code format conventions. If you use Eclipse `m2eclipse` should take care of all settings automatically.
You can also import formatter settings using the [`eclipse-java-style.xml`](https://github.com/OpenFeign/feign/blob/master/src/config/eclipse-java-style.xml) file.
If using IntelliJ IDEA, you can use the [Eclipse Code Formatter Plugin](http://plugins.jetbrains.com/plugin/6546) to import the same file.
