# How to Contribute

## Pull Requests

1. Fork this repository.
2. Create a new branch for each feature or improvement.
3. Send a pull request from each feature branch to the **master** branch.

It is very important to separate new features or improvements into separate 
feature branches, and to send a pull request for each branch. This allows me to 
review and pull in new features or improvements individually.

## Style Guide

All pull requests must adhere to the [PSR-12 standard](https://github.com/php-fig/fig-standards/blob/master/accepted/PSR-12-extended-coding-style-guide.md).

## Unit Testing

All pull requests must be accompanied by passing unit tests and complete code 
coverage. The Slim Framework uses PHPUnit for testing.
