Headlines and Paragraphs
Headlines are placed on a line of their own and surrounded by one to five equal signs denoting the level of the headline. The headline is in between the equal signs, separated by a space. Example:
== Second Level ==
-
A common error is to insert an additional blank after the ending equal signs!
Paragraphs are lines separated by empty lines or other block structures. This means those lines which directly follow each other belong to one paragraph.
Preformatted text (e.g. a copy of an email) should be placed inside three curly braces {{{ ... }}}:First Line ... Last Line
For better visual separation, horizontal lines can be generated by using four dashes.
