At Statusify, contributions are always welcome. We're open to all sorts of changes, big or small, as long as they affect the project positively. Statusify is built by people like you, that's the beauty of open-source software.
If you have some change in mind for the project, begin by forking it. Clone it to your local machine, make the changes you want, push and create a pull request. We'll look into it as soon as possible, and make our best efforts to merge it. If you find a problem, just create an issue and it'll be resolved before you know it.
We work on the development branch, and merge to the master branch once we're sure that the code is fit to run in production. Every merge to master represents a release, and is semantically versioned.
You should adhere to this project's styleguide (you'll be notified via a message by Hound if you don't) and write tests for every new feature you introduce. You must document all code you write. That's it.
