-# aqua_farming
+# Aqua Farming
 A mod for minetest to farm under water.
+
+## Description
+
+Under water is sometimes a little boring. Granted, since minetest 5.x at least corals have been added, but how would it be to have a whole garden under water that you can even plant yourself?
+
+This mod gives you the possibility to plant and harvest even under water. The special thing about it is that these plants also only thrive under water.
+
+## API
+You can define and register your own plants and let them growing.
+
+aqua_farming:register_plant({
+                                basenode,      (a Node like default:sand or default:dirt, where the plant is growing)
+                                nodename,      (the Name of the plant itself)
+                                description,   ( ... )
+                                steps,         (How many steps has the Plant to grow.)
+                                min_light,     (do they really need full sunshine to grow?)
+                                drop,          (Define your drops.)
+                                delay,         (Every x seconds it is checked whether)
+                                chance         (the plant is going to the next stage.)
+                            })
