I will post my guide here in a minute, posted it on WS forum also.
In directory, you must put [ iurl=#text1] your own text [/iurl] for every line. Don't put space between [ and i, I just put it, so you can see it. Make sure you do not forget the #, else it will not work.
In my example:
[iurl=#hello]Point 1 - Hello[/iurl]
[iurl=#behaviour]Point 2 - Commands[/iurl]
Now, about the real paragraphs. You put [ anchor=text1] the title [/anchor] for the beginning of paragraph.
In my example:
[anchor=hello]Point 1 - Hello[/anchor]
Some stuff here.
[anchor=behaviour]Point 2 - Commands[/anchor]
Some stuff here.
