-Vim is for everybody, no matter race, gender or anything.  Some people make a
-big deal about using "he" or "his" when referring to the user, thinking it

-writing help text, which quite often is many years old.  Also, a lot of the
-text is written by contributors for whom English is not their first language.
-We do not make any assumptions about the gender of the user, no matter how the
-text is phrased.  Some people have suggested using "they", but that is not
-regular English. We do not want to spend much time on this discussion.  The

+GENDER NEUTRAL LANGUAGE
+
+						*gender-neutral* *inclusion*
+Vim is for everybody, no matter race, gender or anything. For new or updated
+help text, gender neutral language is recommended. Some of the help text is
+many years old and there is no need to change it. We do not make any
+assumptions about the gender of the user, no matter how the text is phrased.
+The goal is that the reader understands how Vim works, the exact wording is
 secondary.
 
+Many online technical style guides include sections about gender neutral
+language. Here are a few: >

+Note: gender neutral language does not require using singular "they".
