-## [web-app-cast](./packages/web-app-cast/)
-
-This app enables Google Cast integration for ownCloud Web.
-
-## Usage instructions
-
-There is a docker image hosted on [Docker Hub](https://registry.hub.docker.com/r/owncloud/web-extensions).
-It serves compiled assets statically.
-
-This is the list of available app paths provided by the service:
-
-```
-/extensions/cast/cast.js
-```
-
-### ocis_traefik
-
-If you want to deploy web-extensions to the [ocis_traefik](https://github.com/owncloud/ocis/tree/master/deployments/examples/ocis_traefik) example, you need to add a service like this to the `docker-compose.yml` file.
-
-```yaml
-   web-extensions:
-     image: owncloud/web-extensions:latest
-     networks:
-       ocis-net:
-     labels:
-       - "traefik.enable=true"
-       - "traefik.http.routers.web-extensions.entrypoints=https"
-       - "traefik.http.routers.web-extensions.rule=Host(`${OCIS_DOMAIN:-ocis.owncloud.test}`) && PathPrefix(`/extensions`)"
-       - "traefik.http.routers.web-extensions.tls.certresolver=http"
-       - "traefik.http.routers.web-extensions.service=web-extensions"
-       - "traefik.http.services.web-extensions.loadbalancer.server.port=8080"
-```
-
-You can verify this works correctly by checking `https://ocis.owncloud.test/extensions/cast/cast.js` is a minified javascript file.
-
-Now you can create a `web.config.yaml` file in the `ocis_traefik` folder with the following content. The `cast` app is used as an example here. You need to add a block to the `external_apps` for every app you want to use. 
-
-```yaml
-web:
-  config:
-    external_apps:
-      - id: cast
-        path: https://ocis.owncloud.test/extensions/cast/cast.js
-```
-
-and mount that to your oCIS container by adding a volume to it like this:
-
-```yaml
-  ocis:
-    [...]
-    volumes:
-      - ./web.config.yaml:/etc/ocis/web.yaml
-      [...]
-```
-
-If something does not work as expected, you can try to run `docker-compose up --force-recreate` and check again.
