Bonjours to both of you,
OK, no problem with just text and not in PDF. I write the tool description in OpenOffice and can easily send the plain text without any image.
As for the wiki, I ask myself two questions:
1-do I publish as I go along, at the moment I have done Lines, Circles, Arcs and Ellipses. Waiting until, hopefully, I went through the whole set of tools may take a while, especially as I struggle with the Polylines.
2-With the poor experience I had with Git, I wonder if I will be able to handle the Wiki bit
