Create an account on the pool you want to use e.g: www.multipool.us
Then create a Worker and set the settings accordingly, Wallet address, etc

Start guiminer-scrypt, GUIminer will run, and will give you some fields to complete.
In host, we enter the server name in, WITHOUT HTTPS or tcp:// or port, So we will put it as: pool1.us.multipool.us

In Port we will put 3333 or whatever port for the coin & pool your mining at, in username field we put our workers name e.g: Hoppz.1 and the password we created for it.

Make sure that the stratum box is ALWAYS on YES and you can select from some pre-defined settings for our GPUs!

All the other information like vector, worksize, thread-concurrency, etc will be Automatically Entered.
