This is topic one
some more interesting stuff I wonder why I don't get a toc?
==== topic 1.1.1 ====
three levels down
this should give me two children in the tree
==== topic 1.2.1 ====
three levels down, will that trigger a toc?
==== topic 1.2.2 ====
will this?
Yes, I added a sufficient number of headers to get a table of contents. apparently there needs to be at least 3 nesting levels. I could possibly reduce it to 2.
