This documentation was defined in this proposal. It is an introduction to WordPress and the DLF website.
The document is in two parts. The "wp4dlf-credentials.pdf Δ" file includes only an appendix with many usernames and passwords for DLF accounts on various services. It is very sensitive in that these passwords would make it possible for anyone who has them to put anything they want on the DLF website. Be cautious with this one!
The rest of the document is "wp4dlf.pdf" and is safe to share with anyone who needs to know more about the DLF site.
The documentation was created in Apple Pages and the "wp4dlf.pages Δ" document includes both parts above in a single editable file, if you have Pages. If you want to try editing this with MS Word, you can the "wp4dlf.doc Δ" file, but be warned that much of the formatting of the original is lost in translation.
