[NTG-context] building from source

Dear Context developers, I want to build Context MkXL from source and use that. I went to the download page http://www.pragma-ade.com/download-1.htm and downloaded the 2023-03-20 version: http://www.pragma-ade.com/context/latest/cont-tmf.zip This contains README.adoc which tells me that information can be found on https://wiki.contextgarden.net. I don't find any further information about building from source, either in the dowloaded material, or on the wiki or the pragma-ade.com site. What am I overlooking? Thanks, Rainer -- Rainer J.H.
