+# Desktop in OOD
+
+You can get a basic desktop interface to HPC resources.
+
+## Getting Started
+You can get a desktop in OOD by going to the URL [ood.hpc.nyu.edu](http://ood.hpc.nyu.edu) in your browser and selecting `Desktop` from the `Interactive Apps` pull-down menu at the top of the page.  As you can see below, once you've used it and other interactive apps they'll show up on your home screen under the `Recently Used Apps` header.
+
+:::note
+Be aware that when you start from `Recently Used Apps` it will start with the same configuration that you used previously.  If you'd like to configure your Desktop session differently, you'll need to select it from the menu.

+## Configuration
+
+You can select the number of cores, amount of memory, GPU type (if any), number of hours, and optional Slurm options.

+
+## Desktop running in OOD
+
+After you hit the `Launch` button you'll have to wait for the scheduler to find node(s)for you to run on:
+![OOD Desktop in queue](./static/ood_desktop_in_queue.png)
+
+Then you'll have a short wait for the Desktop itself to start up.<br />
+Once that happens you'll get one last page that will give you links to:
+-   open a terminal window on the compute node your Desktop session is running on
+-   go to the directory associated with your Session ID that stores output, config and other related files for your session
+-   make changes to compression and image qualtiy
+-   get a link that you can share that will allow others to view your Desktop session
