 ## Step 1 — Installing GoCD
 
-There are several ways to install GoCD. As a Go binary, it is fine to run on its own, but this makes keeping the service up to date more difficult. You can also install it in a Docker container, which is a good way to keep the server containerized if you are running multiple applications on a single server.

 For the purposes of this tutorial, however, we will be installing the service via the APT repository. This allows easier updates and lets the service run without the overhead of a Docker container.

 Every instance of GoCD needs at least one **agent**. Agents are the mechanism by which the server runs pipelines. They spin up an environment in which to execute the commands specified within the pipeline, and once they are finished running those commands, they clean up the environment.
 
-As before, there are several different ways to install agents, each with their own benefits and drawbacks. For instance, installing with Docker will allow multiple agents to be running at a time and is suitable for multiple agents running at the same time. This may be preferable if you foresee running multiple pipelines concurrently. As before, you can also run agents through a Go binary downloaded from the GoCD website.

+### Setting Up Your Domain Name and HTTPS
+
+In order to view the GoCD web interface, you will need a domain name pointed at your server as mentioned in the prerequisites. Once you have that DNS record properly in place, you will need to open the firewall ports to allow HTTP(S) connections:
+
+```command
+sudo ufw allow 
+
+edit a configuration file that the GoCD agent has installed in order to listen for requests on the proper address and ports.

+Open the configuration file for editing. The following example uses `nano`. This file will contain environment variables that `go-server` relies on for its operation:
+
+```command
+nano /usr/share/go-server/wrapper-config/wrapper-properties.conf
