First, download the provided modlist and save it to an easily accessible location. Then, open your Modrinth launcher. If this is your first time launching it, you'll need to link your Minecraft account by clicking the Steve icon at the top right. Once logged in, the icon will be replaced with your in-game player head. Next, click on the '+' at the bottom left. 

Next, a 'Create Instance' tab will open. Select the 'From File' option, then choose the modrinth file. Click 'Create' and wait for it to import. 

Once it's imported, you're ready to go. Click 'Play,' and you're set!
