+### Custom mob plugins
+The custom mob system of DungeonsXL is command based and thus works with any external plugin that provides a spawn command out of the box. Simply add the command to this main config section:
+
+```
+# You can register a provider tag and the spawn command to use here.
+# The custom external mob providers should work with the mob sign and the M trigger.
+# The mobs spawned by a custom external mob provider should be recognized by the kill counter (/dxl game).
+externalMobProviders:
+    # providerTag: spawn command
+    # "%%"indicate placeholders
+    XY: custommobplugin spawnmob %mob% %world% %x% %y% %z%
+    # Some mob plugins for some reason forbid decimals. 
+    # In such a case, use the block placeholders instead.
+    YZ: othermobplugin summon %mob% %world% %block_x% %block_y% %block_z%
