Add guidance on avoiding redundant words

[julian-cable]

Guidance to add:
Avoid the words "actually", "just", "really", "simply" and "very". They are filler words that add no value to a sentence.

Original example:
"Remote users can connect to network resources simply by authenticating to their local machine."

Improvement example:
"Remote users can connect to network resources by authenticating to their local machine."
