-1: Click the orange 'Continue' button to the right.
-1: This is a busy page, but there's only one thing you may have to change: the "key pair" setting, which is all the way down at the bottom. Change the selected key pair, if necessary, to be one you named in step 1.3.
-1: This step is where you will start spending money. Scroll back up; there will be section to the right titled "Price for your Selections." That's what Amazon will charge starting when you click the orange 'Launch with one-click' button.

+1: Scroll down to 'Security Group Settings' and click on the 'Create New Based On Seller Settings' button. You'll have to name and escribe the security group; "HTCondor Security Group" would be a fine name. "Allows SSH and HTCondor from anywhere" is a true description. To be more secure, click on the two drop-down boxes set to 'Anywhere' and change them to 'My Ip'. (This will prevent you, and anyone else, from logging into the head node from any other (IP) address. If you're on a laptop, your (IP) address may change as you move around.) Finally, click 'Save'.
+1: Scroll down to 'Key Pair Settings' and make sure the key pair you created in section 1.1 is selected.
+1: You will start spending money when you click on the orange 'Launch' button.
