 # Frontend Architecture
 
-Located in `src/Exceptionless.Web/ClientApp`. The Svelte SPA is the primary client.
+Exceptionless.Web currently has two frontend codebases:
+
+- `src/Exceptionless.Web/ClientApp.angular` is the legacy Angular UI and still powers most of the site. The main folders there are `app/`, `components/`, `less/`, `img/`, `lang/`, and `grunt/`.
+- `src/Exceptionless.Web/ClientApp` is the Svelte 5 app that is still under development.
+
+Use this skill for `ClientApp` work.
