arcade question

I read how to install the arcade, but forgive me if this question has been posted many times before. This part...
Step 2:
"Now we need to set up the link, add a button to your navbar and make the url the url of the forum. (Admin Panel Headers)"

Can I please have a step by step on how to do this?
I am slowly getting the hang of this forum thing.

Basically, copy the link to the forum where the games are. Go into Admin Panel > General Admin > Headers.

There is a form at the bottom, paste the url of the forum into it, name the link Arcade and put any image you want in.

It should look like this:

Picture selected * = http://URL_OF_YOUR_IMAGE

Redirection URL * = http://LINK_TO_THE_FORUM

Alternative text * = Arcade

Hope this helps
