Messages setup guide
Messages is a program that comes pre-installed on recent versions of the Mac OSX operating system, and an easy way to get started with Olark.
Go to the "Preferences" page
Click "Accounts" then the "+" button at the bottom left
Select "Jabber" as the Account Type
Type your Olark username with "@olark.com" at the end, and your Olark password
You're done! If you want to see your buddylist, click "window" then "buddies"
