-Tool for turning cooking of seeds and plants on/off depending on how much you
-have of them.
+Watches the numbers of seeds available and enables/disables seed and plant cooking.
 
-See 'seedwatch help' for detailed description.
+Each plant type can be assigned a limit. If their number falls below that limit,
+the plants and seeds of that type will be excluded from cookery.
+If the number rises above the limit + 20, then cooking will be allowed.

+:start:     Start watching.
+:stop:      Stop watching.
+:info:      Display whether seedwatch is watching, and the watch list.
+:clear:     Clears the watch list.

+    add ``MUSHROOM_HELMET_PLUMP`` to the watch list, limit = 30
+``seedwatch MUSHROOM_HELMET_PLUMP``
