Step 1: Acquire RAM for upgrade (or replacement).
Step 2: Prepare your workspace.
Step 3: Connect the ground.
Step 4: Ground yourself with anti-static wristband.
When wearing the wristband, make sure it's not too tight. Wear it entire time while you're working on internals of your computer. Even though you're well grounded, I would recommend not touching any electronic parts with your hands, as you're leaving natural oil behind. Washing hands before this job is highly recommended.
