-    !!! tip "NVENC"
-        If you want to use NVENC instead of VA-API, uncomment the `runtime` line and remove the `devices` section above. You will need to install the [NVIDIA Container Toolkit](https://docs.nvidia.com/datacenter/cloud-native/container-toolkit/install-guide.html) on your host.
+    !!! question "What to set in `NEXTCLOUD_HOST`?"
+        The `NEXTCLOUD_HOST` environment variable must be set to the URL of your Nextcloud instance. If you are using a reverse proxy, you must set this to the URL of the reverse proxy. If you are using a self-signed certificate or http, you must also set `NEXTCLOUD_ALLOW_INSECURE=1`. This URL is used to download the transcoder binary and to connect to the Nextcloud instance.

If you are using a self-signed certificate or http, you must also set `NEXTCLOUD_ALLOW_INSECURE=1`. Note that you may directly use the name of the Nextcloud container if you are using Docker Compose, but you will need to add the domain to `trusted_domains` in `config.php`.

 !!! info "Usage with Nextcloud AIO"
 
-    With Nextcloud AIO, you will need to put the container into the `nextcloud-aio` network. Also the datadir of AIO needs to be mounted at the same place like in its Netxcloud container into the go-vod container. Usually this would be `nextcloud_aio_nextcloud_data:/mnt/ncdata:ro` or `$NEXTCLOUD_DATADIR:/mnt/ncdata:ro`.
