when I press the hotkey to open the menu it immediately takes me to the "?" page or something, idk, I'll attach a screenshot.

That's normal.

Here's how you start: https://github.com/ToCraft/woodwalkers-mod/wiki/Getting-Started

If you want to use the menu, you need to set "enableUnlockSystem" to "false" (in the config-file).

Please write if that worked for you. :D

That worked for me.

I was a bit confused since the screenshots and the description mention nothing of this feature.
