  +### Continuous Integration
  +
  +Circle CI handles this project's builds. It has two workflows set up: one for commit pushed, and one that it scheduled to run during the night.
  +
  +The commit workflow will trigger every time you push to a branch. If that branch push was triggered by `greenkeeper` it will build it, and if it succeeds it will re-push with the updated `yarn` lockfile and build again.
  +
  +The nighly build workflow will run every night at 4 AM and will build the latest changes added to the `master` branch.
