 1. **Hand it off** If you're the first reviewer and everything looks good but the changes are more than a few lines, hand the pull to someone else to take a second look. Again, try to find the right person to assign it to.
 1. **Merge the code** When everything looks good, put in a `LGTM` (looks good to me) comment. Merge into the target branch. Check the labels on the pull to see if backporting is required, and perform the backport if so.

 What this shim does is fairly simple if you go line by line:
 
 . makes sure that jQuery is loaded before angular (which actually runs the shim above)
-. load the angular.js file from the npm installation
+. load the angular.js file from the node_modules directory
 . load the angular-elastic plugin, a plugin we want to always be included whenever we import angular
 . use the `ui/modules` module to add the module exported by angular-elastic as a dependency to the `kibana` angular module
-. finally, export the window.angular variable. This means that writing `import angular from 'angular';` will properly set the angular variable to the angular library, rather than undefined which is the default behavior.
