+# How to contribute
+
+First off, thanks for taking the time to contribute!
+
+## Submitting changes
+
+Please send a GitHub Pull Request with a clear list of what you've done (read more about [pull requests](http://help.github.com/pull-requests/)).
+
+Always write a clear log message for your commits. One-line messages are fine for small changes, but bigger changes should look like this:
+
+```
+$ git commit -m "A brief summary of the commit
+> 
+> A paragraph describing what changed and its impact."
+```
+
+## Coding style
+
+Start reading the code and you'll get the hang of it. It is optimized for readability:
+
+* Variables must be uppercase and should begin with `MY_`.
+* Functions must be lower case.
+* Check your shell scripts with [ShellCheck](https://www.shellcheck.net/) before submitting.
+* Please use tabs to indent.
+
+One more thing:
+
+* Keep it simple! 👍
+
+Thanks! ❤️❤️❤️
