Need help building an addon

[jovial temple]

I'm trying to create an addon, but I'm not sure how to approach it. I want https://github.com/burntcookie90/librofm-downloader to run on my home assistant and download my books automatically to my nas (mounted on the ha).

I've tried several things, you can see it here: https://github.com/megawubs/hass-addons/tree/main/librofm-downloader but nothing I do results in a working image. Can someone help me out? Right now, the add-on doesn't even show up on the add-store page.

Head to id:customize and select "I want to contribute dev skills to Home Assistant". You will get the Developer role and access to support channels for devs.
