How to install the pack from GitHub (Ignore this) - Norway174/Peanut-Craft GitHub Wiki
This doesn't work. Ignore this. The problem is the format of the .ZIP you download from GitHub. Use the Curse page once that's available!
Just keeping this here for archive purposes. It will be deleted later.
Step 1:
Download the .ZIP file from the Master branch.
Step 2:
Open Curse / Twitch Launcher, and navigate to "Mods", then select "Minecraft".
Step 3:
Click "Create Custom Profile".
Step 4:
Import the .ZIP you downloaded.
And that's it! The profile should now appear, and download the required mods from Curse.
