+# Map Andreas Plugin  #
+This plugin was initiali made by Kalcor and extended bv Mauzen.
+It allows you to load different height maps and check the min height for x,y coordinates.
+You can us it as example for an anti cheat to detect airbreaks easier or to prevent falling through the ground.
+
+## Features
+- Load height map
+- You can also implement it in your sampgdk plugins.
+
+## Functions
+|native|params|return|
+|-------|-------|:-----:|

+### Example
+Initialize MapAndreas and get a position.
+
+    public OnGameModeInit(playerid, cmdtext[])
+    {
+        MapAndreas_Init(MAP_ANDREAS_MODE_FULL, "scriptfiles/SAFull.hmap");
+        new Float:pos;
+        if (MapAndreas_FindAverageZ(20.001, 25.006, pos)) {
+            // Found position - position saved in 'pos'
+        }
+        return 0;
+    }
