Every time a branch/pull request is being merged to the master branch, Travis execute the deployment script atdeploy/deploy.collections.js.
This script connects to a MySQL database, checks to see what changed in collection/, and updates the database. (removes/changes/adds data, so it'll be exactly like collection/)

The MySQL database from above, is being used by the API to deliver the data. (see code)

I'd love if someone could write about it in the README file (dive into the code to understand more)

More information about how to run the API (for example, how to run it locally): #198
