 All of our npm dependencies are locked via the `yarn.lock` file for the following reasons:
 
 - our project has lots of dependencies which update at unpredictable times, so it's important that
-  we update them explicitly once in a while rather than implicitly when any of us runs npm install
-- locked dependencies allow us to reuse npm cache on travis, significantly speeding up our builds

+- locked dependencies allow us to reuse yarn cache on travis, significantly speeding up our builds
   (by 5 minutes or more)
 - locked dependencies allow us to detect when node_modules folder is out of date after a branch switch
   which allows us to build the project with the correct dependencies every time
