 ## Trying out Watchtower
-
-### Starting Watchtower in Dev Mode
-
-The following steps assume that you are running Watchtower in `dev` mode.
 Running Watchtower in a more permanent context requires a few more steps, such
 as writing some simple configuration files to tell the nodes how to reach their
 database and KMS. The steps below, along with the extra information for needed
 for permanent installations, are detailed in our [Installation Guide].
 
-1. Download the latest release of the server binary and appropriate desktop
-   client(s) from our [releases page]
-2. Start the server binary with `watchtower dev`. This will start a Controller
-   service listening on `http://127.0.0.1:9200` for incoming API requests and a
-   Worker service listening on the same address/port for incoming session
-   requests. It will also create various default Catalogs and Sets, and display
-   various bits of information, such as a username and password that can be
-   used to log in.
