+## Installation
+Run the `minecartd_install` script. It downloads and installs `minecartd`, sets up a new user account, generates default config file and servers directory, and installs and enables a `systemd` service for `minecartd`.  
+In general, using the service is the preferred method. However, on systems without `systemd`, or when testing the software, you may opt to disable it (`systemctl stop minecartd && systemctl disable minecartd`) and use the command line instead (`/usr/bin/minecartd` or `java -jar minecartd.jar`).
 
 
 ## Usage
-On the server, run `minecartd`.
+On the server, run `minecartd`, either from command line or via `systemd` service.
 Then on the client, connect to it with an appropriate tool (ex. `telnet`) to access the Command Interface
