Hey Zenkardo, here's a bit more clarity:
Importantly, when downloading JourneyMap, there are two different versions - one for Fabric and one for Forge. Only the Fabric version works with the Wurst Client, so be sure to download that one.
Then, to find your mods folder:
- On Windows, it's at
- On Linux, it's at
- On Mac, it's at
Once you've placed the JourneyMap mod in your mods folder, there are no extra installation steps. You should be good to go.
Hope this helps!
