This consists of normal characters like asterisks, single quotes or equal signs which have a special function in the wiki, sometimes depending on their position. For example, to format a word in italic, you include it in two pairs of single quotes like ''this''. The Edit toolbar can greatly simplify formatting your text without knowing wiki markup. But it is easy to pick up the basics, and they will be helpful when you are editing text someone else has already formatted. PetroWiki ignores single line breaks.
