 # WuttaFarm
 
-This is a starter project based on
-[WuttaWeb](https://wuttaproject.org).
+This is a Python web app (built with
+[WuttaWeb](https://wuttaproject.org)), to integrate with and extend
+[farmOS](https://farmos.org).
+
+It is just an experiment so far; the ideas I hope to play with
+include:
+
+- display farmOS data directly, via real-time API fetch
+- add "mirror" schema and sync data from farmOS to app DB (and display it)
+- possibly add more schema / extra features
+- possibly sync data back to farmOS
