 This repository is prepared for Umbrel app-store usage.
 
-1. Put this project into your app folder (folder name must match `id` in `umbrel-app.yml`, currently `nx-webmail`).
+1. Keep this app in a folder named exactly like the app ID: `nx-webmail`.
 2. Keep these files in that folder:
    - `docker-compose.yml`
    - `umbrel-app.yml`
    - `Dockerfile`
-3. Add the app folder to your Umbrel community app store repo and push.
+   - `exports.sh`
+3. Ensure your store root contains `umbrel-app-store.yml`.
+4. Push the app-store repo to a git host reachable from Umbrel.
+
+## Install from Umbrel UI
+
+1. Open App Store in Umbrel.
+2. Use the menu to add a Community App Store.
+3. Paste your repository URL.
+4. Open your store and install `Webmail`.
 
 Notes:
 - Umbrel uses the `app_proxy` service in `docker-compose.yml`.
 - Internal app port is `3001`.
-- If your store prefix is not `nx`, change `id` in `umbrel-app.yml` and update `APP_HOST` accordingly.
+- If your store prefix changes, update `id` in `umbrel-app.yml` and `APP_HOST` in `docker-compose.yml`.
