 How to connect to HCC resources
---------------------------------------
 
-{{% children description="true" %}}
+**1. Create an Account:** The use of HCC resources requires an HCC account to be created. To create an account, follow the steps in [Creating an Account]({{< relref "/accounts/_index.md" >}}).
+
+**2. Open a terminal or SSH client** Most interactions with HCC clusters are done through SSH and the command line. In MacOS, Linux, and recent versions of Windows 10, there is an SSH client built-in and can be used from their [respective terminals]({{< relref "terminal.md" >}}). For older versions of Windows, an application such as [PuTTY]({{< relref "putty.md" >}}) or [MobaXterm]({{< relref "mobaxterm.md" >}}) is needed.
+
+**3. Connect to an HCC cluster:** From the terminal or application, use SSH to connect to one of the available clusters. In the terminal, enter `ssh <username>@crane.unl.edu` to connector to the Crane cluster, for example. With [PuTTY]({{< relref "putty.md" >}}) or [MobaXterm]({{< relref "mobaxterm.md" >}}), refer to their respective pages for a guide on how to connect
