Documentation: Improve setup instructions

Did you follow the steps in the README.txt file? ;)

For the content type you are using for your rooms, you should enable the availability calendar setting (at admin -> content -> content types), and then each node of that type, you should see availability calendars appear. To set the availability, you first need to make sure you have the correct user permissions set. Then, when viewing the node, you can click the edit link for each month to change the availability for each day.

Let me know if this helps or not.

Please re-open if you're still having issues.

What's not said in README.txt (or anywhere else that I could find) is that the option to enable the availability calendar for a content type is actually under Admin -> Content Management -> Content Types -> [Edit existing or create new content type] -> Workflow.

It took me a very long time to figure out that "You will find the option under 'Availability calendar support'." (from the readme) actually meant that the line 'Availability calendar support' was not a [foldable] block of its own, but actually just a headline under the folded Workflow block.

TwoD, thanks for the feedback, I'll update the readme to try and make it clearer.

I've improved the documentation to better describe the steps, and I've actually moved the Availability Calendars settings into their own collapsible fieldset as well. This is in the dev version, but will be in a release soon.
