 ```shell
 $ npm run coverage
 $ open coverage/index.html
 ```
 
-This will allow you to browse to red sections of the code that need
-more attention. Even more cool, however, is to run:
-
-```shell
-$ npm run dev
-```
-
-(On some operating systems, this may pop up a request for node to be able to open a socket. Click "Allow" or the equivalent.)

-This will run the coverage tools, and monitor all of the files in the
-project, re-running the coverage tools and refreshing the browser when
-any files change. There will be a small web server running on port 4103 to enable this. Control-C to stop.
