-WorldEdit has a huge potential for abuse by untrusted players. Therefore, users will not be able to use WorldEdit unless they have the `worldedit` privelege. This is available by default in single player, but in multiplayer the permission must be explicitly given by someone with the right credentials, using the follwoing chat command: `/grant <player name> worldedit`. This privelege can later be removed using the following chat command: `/revoke <player name> worldedit`.

-Certain functions/commands such as WorldEdit `//lua` and `//luatransform` chat commands additionally require the `server` privilege. This is because it is extremely dangerous to give access to these commands to untrusted players, since they essentially are able to control the computer the server is running on.

 Node names are required for many types of commands that identify or modify specific types of nodes. They can be specified in a number of ways.
 
-First, by description - the tooltip that appears when hovering over the item in an inventory. This is case insensitive and includes values such as "Cobblestone" and "bronze block". Note that certain commands (namely, `//replace` and `//replaceinverse`) do not support descriptions that contain spaces in the `<searchnode>` field.

-Second, by name - the node name that is defined by code, but without the mod name prefix. This is case sensitive and includes values such as "piston_normal_off" and "cactus". Nodes defined in the `default` mod always take precedence over other nodes when searching for the correct one, and if there are multiple possible nodes (such as "a:celery" and "b:celery"), one is chosen in no particular order.

-The node name "air" can be used anywhere a normal node name can, and acts as a blank node. This is useful for clearing or removing nodes. For example, `//set air` would remove all the nodes in the current WorldEdit region. Similarly, `//sphere 10 air`, when WorldEdit position 1 underground, would dig a large sphere out of the ground.

+This is a step-by-step tutorial outlining the basic usage of WorldEdit.
 
 Let's start with a few assumptions:
 
-* You have a compatible version of Minetest working.
-  * See the [README](README.md) for compatibility information.
+* You have a compatible version of Minetest working, that is 5.0 or later.
 * You have WorldEdit installed as a mod.
-  * If using Windows, [MODSTER](https://forum.minetest.net/viewtopic.php?pid=101463) makes installing mods totally painless.
   * Simply download the file, extract the archive, and move it to the correct mod folder for Minetest.
   * See the installation instructions in [README](README.md) if you need more details.
 * You are familiar with the basics of the game.
