Editing signature here in forum?

Guys, how do you do html style effects in the signature, like italic, bold, adding a small picture, links etc?

Just use syntax of site

Yeah but what is the syntax? i know html, css and am used to alternatives like bbcode. But I can't understand this site!

It looks like Markdown.
