when I tried to make my own addon and change it to a .jar file lowcode mod, I put it in the mods folder and it didn't work. I need an in-depth tutorial on how to do this, like a video. someone please help!

I apologize for the lack of documentation on Breed creation. I unfortunately have not had the time to write up anything detailed for how to make new breeds. This issue (as well as #135) will be top priority once I got the next update out.

I thank you for your patience in regards to this.

As for your issue, make sure that there is no extra folder after your jar.
The structure should look like this:

-- my_custom_breeds.jar
    | -- META-INF/
    | -- assets/
    | -- data/
    | -- pack.mcmeta

I hope this helps.

Closing as a duplicate of #135

it still doesn't work! when I clicked on the jar file it said "invalid or corrupt jarfile"

it still doesn't work. I need a video guide on how to do this. I really don't get it
