-To be moved to an appropriate section of "how to write documentation" or
-"how to contribute to the documentation":
-
-1. When writing documentation, please use gender-neutral wording when
-   referring to people, such as singular “they”, “their”, “them”, and
-   so forth. -> https://en.wikipedia.org/wiki/Singular_they
-
-2. Keep line length below 74 characters.
-   - Expection by texi2pdf output so far: URLs will break
-     (inserted whitespace) when they contain linebreaks
-     within the @url{} / @uref{}.
-
-3. Do not use tab characters (see chapter 2.1 texinfo manual)
-
-4. Use neutral language and third person perspective in the text
-
-4.1 So, when you refer to a user in general or addressing the user,
-    refer to (1).
-4.1.1 Unsolved exceptions for canonical reasons:
-      When refering to Alice, use "she".
-      When refering to Bob, use "he".
-      These are long established examples and they
-      should either be replaced (avoid Alice and Bob
-      examples when you can) or followed.
-
-5. Use 2 spaces between sentences, so instead of:
-
-     We do this and the other thing. This is done by foo.
-
-   Write:
-
-     We do this and the other thing.  This is done by foo.
-
-6. Use @footnote{} instead of putting an @*ref{} to the footnote on a
-   collected footnote-page.
-   In a 200+ pages handbook it's better to have footnotes accessible
-   without having to skip over to the end.
-
-6.1 Avoid unnecessary footnotes, keep the text self-explanatory and
-    in a simple language where possible/necessary.

 * Completion Levels:
 
 ** chapters/philosophy: around 100% fixed after initial export.
