I wanted to setup doscpell (https://github.com/eikek/docspell) in unraid however I think the setup is a bit beyond me as there is no official template.

 

Looking at the official compose I see that its basically a set of multiple containers.

https://github.com/eikek/docspell/blob/master/docker/docker-compose.yml

 

To get this running on unraid I guess I would have to setup each container separately from the gui right?

Is there a way to make this easier by creating a template? Or can a template for unraid just contain one image/container?

I tested Docspell on a VM under Unraid via docker-compose.
As I want to run the dms as a docker directly in Unraid I took a closer look at the docker-compose file.
After a few tests docspell was up and running.

I built templates and wrote instructions on how to install them. 
Sorry, the instructions are in german but I may translate them later.
See here: https://github.com/vakilando/unraid-docker-templates
You can try them. 
They are for my personal use and they are not part of the unraid community-apps and I do not have a support thread for them (yet).
