There are two "sections" of documentation:
1. Wiki at domain wiki.mikrotik.com
2. Help at domain help.mikrotik.com
Which of them should I be using?
In other words, which of them is the most updated?
For example - the Scripting page:
Scripting @ Wiki:
https://wiki.mikrotik.com/wiki/Manual:Scripting
Vs.
Scripting @ Help:
https://help.mikrotik.com/docs/display/ROS/Scripting
