+## ES6
+
+Source code for all .js files in this project is written in es6 and then compiled via babel to es5. Unfortunately, for legacy reasons, the es5 needs to be stored in version control. As such, if you want to change a js file, edit the version in the corresponding .es6 directory, compile it with the `gulp babel` command, and then commit it as well as the resulting .js file.
