* his or hers, use theirs

* himself or herself, use themselves

* **Avoid belittling words**: People read documentation because they know very

little about a specific topic or are even completely new to it. Things that

seem "obvious" or "simple" for the person documenting it, can be the exact

opposite for the reader. To make sure everybody feels comfortable when reading

the documentation, try to avoid words like:

* basically

* clearly

* easy/easily

* just

* logically

* merely

* obviously

* of course

* quick/quickly

* simply

* trivial
