Welcome to the WorldEditAdditions beginners tutorial! There are a number of conventions used in the [chat command reference](/Reference) that may not be immediately obvious - this guide serves to explain in detail.
- You are already familiar the basics of [Minetest](https://www.minetest.net/) (try the [tutorial game](https://content.minetest.net/packages/Wuzzy/tutorial/) if you're unsure)
- You have both WorldEdit and WorldEditAdditions installed (see the [Download](/#download) section)
Minetest supports the execution of _Chat Commands_ to manipulate the Minetest world. While in a Minetest world, simply type `/help` (the first forward slash `/` will automatically cause the chat window to appear) and hit <kbd>enter</kbd> to display a list of chat commands that are currently registered grouped by mod for example.
WorldEdit commands are, by convention, prefixed with an additional forward slash `/`. Here are some examples of WorldEdit chat commands:
```
//1
//2
//set dirt
```
Explaining core WorldEdit commands is out of scope of this tutorial, but you can find a complete list of them here: <https://github.com/Uberi/Minetest-WorldEdit/blob/master/ChatCommands.md>.
The purpose of _WorldEditAdditions_ is to extend _WorldEdit_ by adding additional commands. Example commands that have been implemented that are not present in core _WorldEdit_ include (but certainly aren't limited to):
- [`//scale`](/Reference/#scale-axis-scale_factor-factor_x-factor_y-factor_z-anchor_x-anchor_y-anchor_z): Scale things up and down - even both at the same time!
See a full list with complete explanations in the [chat command reference](/Reference).
WorldEdit allows you to define a _region_ by specifying 2 points in the world - we number these points 1 and 2. By using the WorldEdit wand (or WorldEditAdditions Far Wand), one can left click to set the position of point 1, and right click to set point 2:
