Yep, there's another discussion about documentation (Updating the Tidal website and documentation - #47 by yaxu), there's a plan to move everything on a markdown based static site (https://doc.tidalcycles.org), at the moment the documentation is the wiki on tidalcycles.org, everyone signed in can modify it.
The code I linked is specific to my setup, I did some trial/error to load those synths/effects.
Not particulary complicated, I admit that I had to look at the superdirt code to understand the signature of some functions, but it worked well enough.
