 ### Usage

 #### Starting the Server
+
 To use HyperQueue, you first have to start the HyperQueue server. It is a long-lived process that
 is supposed to be running on a login node. You can start it with the following command:
 
-    $ hq server start
+    `$ hq server start`
 
 #### Submitting Computation
-Once the HyperQueue server is running, you can submit jobs into it. Here are a few examples of
-job submissions. You can find more information in the [documentation][2].
