How to install channels dvr on a Terramaster F2-221 NAS

I have a terramaster f2-221 which is exactly the one on this website, but instead of 2gb ram I upgraded the ram to 10gb, I would like to know what is the best way to run channels dvr on it? I am currently using the docker method but I'm not sure I'm doing it the right way, if the best method is with docker which container should I use? I have also read of some methods to install it through ssh with a tool like putty but the forums where I have read that are years old and the steps that they show on there no longer work, if anyone could help me I would really appreciate it, Thanks in advance!

You have to install it via Docker

which container should I use?

Instructions are here https://hub.docker.com/r/fancybits/channels-dvr

Latest should be fine, unless you need TV Everywhere support. (Streaming US-based channels using a authorized tv provider directly in Channels) Then use the tve tag instead.

Thank you so much
