+# Stratos Desktop
+
+From the top-level Stratos folder:
+
+- Install dependencies with `npm install`
+- Change to the `electron folder` with `cd electron`
+- Install dependencies for the electron UI with `npm install`
+- Run the Electron app with `./run.sh all`
+
+> Note this builds both the frontend and backend and run the app
+
+- To build only the front end before running, use `./run.sh fe`
+- To build only the back end before running, use `./run.sh be`
+- To run without building either the the back end or front end, use `./run.sh`
+
+
+You can also run the UI with `ng serve` from the top-level folder and then start electron with:
+
+`./run.sh dev`
+
+to load the UI from `https://127.0.0.1:4200`

+# Packaging
