How to contribute
I'm really glad you're reading this.
Please send a GitHub Pull Request to plugin-customizer with a clear list of what you've done (read more about 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."
My plugins are following the WordPress Coding Standards.
Thanks, Per Søderlind
