Click the 'Install Steam Now' blue button and allow the Steam installer to download.
Once downloaded, click 'run/open' and follow the instructions to install the Steam client onto your computer.
When the Steam client starts, you will be prompted to log in or create a Steam account.
Registering Steam Account
Before you activate your game key and enjoy hours of fun, you'll need to create a Steam account and be logged in. You can either create a Steam account directly on the Steam website or from within the Steam client - either way, it's simple to get set up.
Enter your email address in boxes 1 and 2, the validation characters need to be copied into box 3, and the agreement needs to be ticked in box 4. Once you have completed the form, click on box 5 'Continue'.
Next, you'll need to check your email and click on the link to complete the account creation.
