+### Download and Install the app
+
+Download with your favourite browser. You can run it directly from your Downloads folder, but for long-term use, and for use by multiple users, it's preferable to move the file to /opt. Open the Terminal (often Accessories-> Terminal, or CTRL+T) and enter:
+```
+sudo mv Downloads/minecraft-pi-reborn-client-2.3.4-arm64.AppImage /opt/
+```
+(replacing Downloads/minecraft-pi-reborn-client-2.3.4-arm64.AppImage with the file you downloaded). 
+
+To run, the file must be executable:
+```
+sudo chmod a+x /opt/minecraft-pi-reborn-client-2.3.4-arm64.AppImage 
+```
+### Run the app
+Enter the name of the AppImage to run, e.g.:
+```
+/opt/minecraft-pi-reborn-client-2.3.4-arm64.AppImage
+```
