+Areas mod for Minetest
+======================
+
+Dependencies
+------------
+
+Minetest 5.0.0+ is recommended, but 0.4.16+ should work as well.
 
 
 Configuration
 -------------
 
-If you wish to specify configuration options, such as whether players are
-allowed to protect their own areas with the `protect` command (disabled by
-default), you should check settings.lua and set the appropriate settings in your
-server's configuration file (probably `minetest.conf`).
+Open the tab `Settings -> All Settings -> Mods -> areas` to get a list of all
+possible settings.
+
+For server owners: Check `settingtypes.txt` and modify your `minetest.conf`
+according to the wanted setting changes.
+
 
 
 Tutorial
 --------
 
-To protect an area you must first set the corner positions of the area.
-In order to set the corner positions you can run:
+1) Specify the corner positions of the area you would like to protect.
+Use one of the following commands:
+
   * `/area_pos set` and punch the two corner nodes to set them.
   * `/area_pos set1/set2` and punch only the first or second corner node to
 	set them one at a time.

 	coordinates.

   * `/set_owner <OwnerName> <AreaName>` -- If you have the `areas` privilege.
   * `/protect <AreaName>` -- If you have the `areas` privilege or the server
 	administrator has enabled area self-protection.

-Now that you own an area you may want to add sub-owners to it. You can do this
-with the `add_owner` command.  Anyone with an area can use the `add_owner`
-command on their areas.  Before using the `add_owner` command you have to
-select the corners of the sub-area as you did for `set_owner`. If your markers
