There is no source-level documentation of postgis available.

Entry point (from a postgresql prospective) is lwgeom/lwpostgis.sql.in
For plpgsql or sql functions all work is there.

For C functions I suggest you set up a completely new file and
include liblwgeom.h from it. Read that header file as a start point.

Feel free to ask more specific questions.
