# Command System

Iris features a command system called Decree, which allows us to make new commands easily, and allows you to see all kinds of helpful information on a command.

### The main command

The main command to access is `/iris`. Running this command shows you the main page of commands.

### Hovering

You can hover over any command or parameter to see:

* A description
* A warning if you do not have permission to use it
* Examples of how to use
* If a parameter is required or not
* If a parameter can be derived from context (such as the world you are in)
* The default value of the parameter (if it has one)
* The type of a parameter (such as String or Integer, or even IrisDimension or World)

### Context

Iris is really good at guessing what you want / filling in the blanks. If you specify a command that is specific for a world, like `/iris pregen`, Iris will guess that the world you are currently in (as a player) is the world you want to use the command on. You can always manually input the value if Iris is guessing wrong, by adding it to the command.

### Clicking

You can click any command to either:

* Run the command (if it has no parameters. I.e. a subsection)
* Suggest the command (put it in your chat box, so you can add further values)
