+                All changes you make on the site get submitted directly to our GitHub repo, and then published through
+                the same automated deployment process as changes made by anyone else. That way, anyone can contribute
+                easily: whether developer or end user.

+                To log in, we redirect you to GitHub's site, and once you're signed in, they'll send you back here. We
+                never see your credentials, and only get the minimum set of permissions necessary to submit changes to
+                the Crafting Guide repo on your behalf.
+            p.
+                GitHub offers free accounts, so even if you don't already have one, you've got nothing to lose!
