+API list
+---
+
+ * `areas.registerHudHandler(handler)` - Registers a handler to add items to the Areas HUD.  See [HUD](#hud).
+
+
+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.
+
+### Example
+
+	local function areas_hud_handler(pos, areas)
+		local val = find_my_protection(pos)
+
+		if val then
+			table.insert(areas, {
+				id = "mod:"..val.id,
+				name = val.name,
+				owner = val.owner,
+			})
+		end
