 # proxmox-dashboard
 
-Just a small flutter dashboard to view my local proxmox server
+A very minimal dashboard to display on my Raspberry Pi using [flutter-pi](https://github.com/ardera/flutter-pi).
+
+## Building
+
+Just as any other flutter project build it using
+```
+flutter build linux
+```
+
+Currently, only linux is supported because that's what I am building on and targetting.
+
+Running the app can be done via
+```
+flutter run
+```
+
+## Deploying
+
+To run the app on the raspberrypi boot it into CLI and follow the instructions from [flutter-pi](https://github.com/ardera/flutter-pi).
+
+Copy the build over to the pi and start it using:
+```
+flutter-pi <path-to-flutter-package>
+```
