 Every command is a class, child of the `Command` class.<br>
+**Generic of class `Command<[]>`:** Defines the *type* of the structure of your cmd.
+    - helps in inferring the types of different fields returned by `this.extract()` *(explained later)*
 `structure` - defines a structure for your command.
 Helpful when extracting the fields of you commands.<br>
 This property will be better understood in the next command. Here there are no fields for this cmd => no structure.<br>
+
+*Reason why we define the structure twice is because, `Generic` helps in inferring the type properly and the property `structure` helps in actual conversion of field (say to number) and raising errors in `strict` mode.
+
 `strict` - set it to true if you want to recieve errors/warnings when:
  - user does not follow the defined structure of the cmd
  - a deleted msg listens for certain state(s)
