Creating a command is simple via built-in commands.
To get started, decide on a name for your command and run
/cm create <name>
Lets say we want to make a command called stick.
/cm create stick

Enabling or disabling the command is as easy as
/cm enable <name>
/cm disable <name>
You could enable the command now, but it wouldnt do anything. The next section goes over editing the command.
