ProofBuddy needs to be able to write to 3 folders on your server.  In this step we're checking to see if those folders are setup to allow that.  Ideally you will see the following screen and need to do nothing.

If all 3 lines are green then you are set and don't need to do anything except press Next.

However, if you see a red Failed next to any of the lines like in the screen below there's a little more work to do.

ProofBuddy requires that these 3 folders have their permissions set to 0777, which in non geek speak means that scripts like ProofBuddy can write to them.  The easiest way to change permissions is with an FTP program like FileZilla.

Once you get the permissions set correctly click on Refresh and ProofBuddy will check again. Once they're all set you should see a screen like the first image and can click on Next to move on.
