+# EmbassyOS Frontend
+
+EmbassyOS has three user interfaces and a shared library, all written in Ionic/Angular/Typescript using an Angular workspace environment:
+
+1. **ui**: the main user interface
+1. **setup-wizard**: used to facilitate initial setup
+1. **diagnostic-ui**: used to display certain diagnostic information in the event EmbassyOS fails to initialize
+1. **shared**: contains components, types, and functions shared amongst the three UIs.
+
