 This container bundles MakeMKV and auto-configures it for you.
 
 ### Notes
-- ⚠️ TODO
-- This container should only be run in home networks as it exposes port 5800 unencrypted
+- This container should only be run in home networks
+- This container requires the [`NEXTCLOUD_MOUNT` variable in AIO to be set](https://github.com/nextcloud/all-in-one?tab=readme-ov-file#how-to-allow-the-nextcloud-container-to-access-directories-on-the-host). Otherwise the output will not be saved correctly.
+- ⚠️ TODO: note down requirements regarding devices and also how to check if they are there...
+- After adding and starting the container, you need to visit `https://internal.ip.of.server:5800` in order to log in with the `makemkv` user and the password that you can retrieve when running `sudo docker inspect nextcloud-aio-makemkv | grep WEB_AUTHENTICATION_PASSWORD`. 
+- After the first login, you can adjust the `/output` directory in the MakeMKV settings to a subdirectory of the root of your chosen `NEXTCLOUD_MOUNT`. (by default `NEXTCLOUD_MOUNT` is mounted to `/output` inside the container. Thus all data is written to the root of it)
+- The config data of MakeMKV will be automatically included in AIOs backup solution!
 - See https://github.com/nextcloud/all-in-one/tree/main/community-containers#community-containers how to add it to the AIO stack
