-- `src/Exceptionless.Web/ClientApp.angular` is legacy. Touch it only when the user explicitly asks for Angular/legacy UI work or the bug exists only there.
-- Do not copy Angular patterns into Svelte. Use the frontend skills for Svelte architecture, TanStack Query/Form, and shadcn-svelte details.
+- `src/Exceptionless.Web/ClientApp` is the only application frontend and serves Svelte at `/`.

 ## UI Development
 
-Frontend work currently spans two apps:
+The Svelte 5 UI in `src/Exceptionless.Web/ClientApp` is the only application frontend and serves at `/`. Aspire starts Svelte together with the API. Primary hash-route bookmarks resolve to the current pages, and existing signed-in sessions are retained.
 
-1. The legacy Angular UI in `src/Exceptionless.Web/ClientApp.angular` is still the main site UI. Most of that app lives in `app/`, `components/`, `less/`, `img/`, `lang/`, and `grunt/`.
-2. The Svelte 5 UI in `src/Exceptionless.Web/ClientApp` is still under development.
+See the [frontend README](src/Exceptionless.Web/ClientApp/README.md) for development, build, and test commands. Published app images contain the Svelte build at the web root; API-only images retain their API landing page.
 
 For a quick API walkthrough, start with [exceptionless.http](exceptionless.http). The [tests/http](tests/http) folder contains additional examples for manual use, such as querying events, uploading source maps, and obtaining OAuth tokens. These are curated examples, not an automated test suite or an exhaustive endpoint catalog. Set the local API URL and sample variables, then run the requests you need. In Visual Studio Code, use the [REST Client](https://marketplace.visualstudio.com/items?itemName=humao.rest-client) extension.
