+If you want to use the built-in burner account (Minecraft name `mattstack`):
+
+```
+$ SERVER=minecraft.example.com ./run_linux.sh

+
 ```
-$ USERNAME=you@domain.com PASSWORD=supersecret SERVER=example.com ./run_linux.sh
+$ SERVER=localhost PORT=12345 ./run_linux.sh
+```
+
+If you have your own alt account:
+
+```
+$ USERNAME=you@domain.com PASSWORD=supersecret SERVER=minecraft.example.com ./run_linux.sh
