Contributions are certainly welcome and encouraged.
This application is hosted by GitHub Pages
meaning the master branch is what GitHub uses to deploy the application as found at https://mattw.io/youtube-metadata.
Pull requests should generally describe the changes being made or the issue being addressed.
Pull requests should be merged into the develop branch so that I may make any additional tweaks or adjustments before
merging into master for GitHub Pages to deploy.
Make the pull request from your own fork of the project.
It is recommended to base it off the develop branch.
However, depending how involved you would like to be, I can consider adding you to the main project if asked.
