 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 config.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.

+Protection Conditions
+---
+
+With `areas:registerProtectionCondition(func(pos1, pos2, name))`
+you can register rules to control whether to allow or prohibit the creation of an area.
+
+Return values:
+* `true` Forcefully allows the area creation. This overwrites the outcome of any
+  previously executed conditions, including the default ones registered by this mod.
+* `false, errMsg` Disable the creation of the area and return an error message.
+* `nil` (or no return value) Enable the creation of the area,
+  unless specified otherwise by the other registered callbacks.
+
+
+HUD
+---
+
+If you are making a protection mod or a similar mod that adds invisible regions
+to the world, and you would like then to show up in the areas HUD element, you
+can register a callback to show your areas.
+
+HUD handler specification:
+
+ * `handler(pos, list)`
+   * `pos` - The position to check.
+   * `list` - The list of area HUD elements, this should be modified in-place.
+
+The area list item is a table containing a list of tables with the following fields:
+
+ * `id` - An identifier for the area. This should be a unique string in the format `mod:id`.
+ * `name` - The name of the area.
+ * `owner` - The player name of the region owner, if any.
+
+All of the fields are optional but at least one of them must be set.
