+
+___
+
+### Server Configuration
+
+**NOTE: Server Name and Max Players will be overwritten by your Pterodactyl Startup settings every time the server is started.**
+
+#### In-Game Setup (Recommended):
+
+Configuring all aspects of the server (MOTD, game rules, map list, admins, etc.) is, by far, the easiest (and safest) to do in-game via the built in admin menu. Perform the following steps to do so:
+
+1. Start the server.
+2. Navigate to `/home/container/GroundBranch/ServerConfig` within Pterodactyl's file browser and open `AdminSetupPassword.txt`.
+3. Copy the code and start your personal Ground Branch game client.
+4. Log into your server via the server browser by searching for it by the name you set in the Startup tab of the server.
+5. Open the console by pressing `` ` `` and run the following command: `admin setup <your_setup_password>`. This will add you as a SuperAdmin.
+6. Running the command `admin` will open the Admin Menu where you can configure everything about the server.
+
+#### Manual Setup (Advanced):
+
+All configuration files for the server can be found here: `/home/container/GroundBranch/ServerConfig`
+
+Please refer to the [Unofficial Ground Branch Wiki](https://unofficialgroundbranchwiki.com/en/dedicated-servers/getting-started) for configuration info.

+### Modding
+
+Modding has not been adequately explored at this time. If you have information on modding you would like to share, please submit a PR to update this README.
+
+What is currently known about modding:
+
+- The server seems to automatically look at the following directory for any available mods to load: `/home/workshop/content/16900/`
+- This directory is un-accessible to Pterodactyl end-users, and I am unaware of a way to point the server to look in a different directory for mods.
+- However, you may be able to set up a mount to this directory with mods in SteamCMD format.
