Hi,
Drew had the idea that we could look into updating the old Developer's Guide.
The .odt file for the 2009 dev's guide was surprisingly difficult to find, but I eventually located it: https://wiki.openoffice.org/wiki/File:DevelopersGuide_OOo3.1.0.odt
It has now been uploaded to "LibreOffice Documentation/English/Developers Guide".
The wiki also had all the chapters as individual .odt files. I downloaded them just in case. Should I upload those as well?
