You need a Roblox executor that supports loadstring and game:HttpGet. CloverHub does not provide one.
Open the Games page and pick a game marked Working (or Updating, old version works). Join it in Roblox and wait until your character has loaded.
Attach your executor, paste this and execute it once:
loadstring(game:HttpGet("https://cloverhub.fun/api/loader"))()Paste your key into the prompt that appears. Your key binds to this device the first time you use it. If you change PC later, reset your HWID on the Dashboard.
