Yes. Which is an Arch distro.

The age verification or something else?

It looks like Arch Linux with some ricing done. So first install Arch and customize from there.

Why

I found it easy to install TRMNL on my Kindle inside of KOReader. The Kindle script would not work. I also found setting up the basic docker container script easy. The main issue for me was you have to change the base URL and base API URL in the KOReader TRMNL code and that part isn’t documented.

After all that work I realized we don’t have access to any of the plugins…? So it seems I can only write my own stuff for the selfhosted version.

They claim they will add extensions/plugins in the future but honestly with how bad the selfhosted UI looks, lack of extensions, and insane CEO, I won’t believe anything until its in my hand.
