+//This command has quite a complicated syntax, in theory it has 4 seperate syntaxes which are all variable:
+//
+//1: /firework clear             - This clears all of the effects on a firework stack
+//
+//2: /firework power <int>       - This changes the base power of a firework
+//
+//3: /firework fire              - This 'fires' a copy of the firework held.
+//3: /firework fire <int>        - This 'fires' a number of copies of the firework held.
+//3: /firework fire <other>      - This 'fires' a copy of the firework held, in the direction you are looking, #easteregg
+//
+//4: /firework [meta]            - This will add an effect to the firework stack held
+//4: /firework color:<color>     - The minimum you need to set an effect is 'color'
+//4: Full Syntax:                  color:<color[,color,..]> [fade:<color[,color,..]>] [shape:<shape>] [effect:<effect[,effect]>]
+//4: Possible Shapes:              star, ball, large, creeper, burst
