Core Syntax & Patterns
The 'If... Then...' Rule
IF (something is true), THEN (do this action).
Use this to make a choice. Check the 'IF' part first. If it's true, you must do the 'THEN' part.
The 'AND' Rule
Thing 1 AND Thing 2
Use this when you need to check two rules. Both Rule 1 and Rule 2 must be true.
The 'NOT' Rule
NOT (this thing)
Use this to remove something from a group. Find everything that does not match the rule.
