[Pharo-users] API docs as HTML

Hi, For the JOSS (Journal of Open Source Software) I need to add to a package documentation the API documentation as an external file (hopefully in HTML). So I would like to export the source code in a way that can be used as API documentation. I remember that some API documentation about Smalltalk/Pharo can be found online, but I don't know how to produce such documents. Any pointers to explore? Cheers, Offray
