For a complete manual about the Wiki syntax, see [this page], in the "WikiText" section. Moreover, when you add a new page to the Wiki, make sure you check, at the bottom, the "WikiText" option (default is "BBCode", and that's 'bad').

About the titles : Wiki pages have to be named like this :

• <english_name>FR for french translation
• <english_name> for english version

Examples : CentralPeakFR, BackgroundFR, ScreenPlay, ScreenPlayFR, KingdomsFR ...

So, rather than calling a page about the banana cultivation "BaNane", prefer the title "BananaFR".
