 There are many more commands in the `scripts` section of `package.json`. Most of these are executed by one of the commands mentioned above.

 A command with a name that starts with `pre` or `post` will be executed automatically before or after the script with the matching name. e.g. if you type `npm run start` the `prestart` script will run first, then the `start` script will trigger.

+## npm-shrinkwrap
+This project makes use of [npm-shrinkwrap](https://docs.npmjs.com/cli/shrinkwrap) to ensure that the exact same dependency versions are used every time you install it.
+
+npm-shrinkwrap creates the file `npm-shrinkwrap.json` to track those versions. That file is updated automatically every time you install a new dependency from the commandline (by using `npm install some-lib --save` or `npm install some-lib --save-dev`). 
+
+If you manually add a package or change a version in `package.json` you'll have to update npm-shrinkwrap's lock file as well. You can do so by running `npm run rewrap`
