fixed slugs, escaped curly braces, reworded

Hi Earle,

Sorry about that, for some reason the updated files I made outside of my github tree weren't copied to my github repo as I intended, such that, yes, there was lots of duplicate text and the slugs were the same.  This update fixes those problems.  The slugs are now distinct, and I edited for your comments about content.

I tried escaping the curly braces in the markdown wrapper file code, e.g. "\{" instead of "{"), hopefully that should fix the problem.  

cheers,
Zoli
