   * his or hers, use theirs
   * himself or herself, use themselves
 
+Moreover, we try to avoid belittling words as much as possible. Usually, the people
+that write documentation write about a topic they are very familiar with. Thus, they
+tend to include words like "simply" or "obviously" as things may seem simple or obvious
+to them. However, the future reader is going to read the documentation because they
+know very little about a specific topic or are even completely new to it which means
+they might feel the exact opposite.
+To make sure everybody feels comfortable when reading the documentation, try to avoid
+words like:
+
+* simply
+* just
+* easy/easily
+* quick/quickly
+* of course
+* logically
+* clearly
+* obviously
+* merely
+* basically
+* trivial
