There's no wrong way for a wiki [engine] to implement Creole (see [goals]).

!!Three suggestions
* [[Mixed Mode]] - allow mixed markup of traditional (regular markup for that particular engine) and Creole (sometimes this method is not possible or desirable)
* [[Edit Creole Mode]] - using a extra creole edit button: an extra "Edit Creole" button is added which translates the current wiki markup to Creole while replacing the advanced syntax (i.e. syntax not supported by creole, but by the native wiki engine) into a [Placeholder]. This implementation mode is explained in the [[[prototype]] page.
* [[Gradual Alignment]] - improve bad syntax from your markup with more user-friendly syntax from Creole. Every small improvement is a big step.

It can be useful to see implementation scenarios.  Some examples were discussed at WikiSym 06 and can be found on the [prototypes].
