 # Dss Flappers
 
-Implementations of MakerDAO surplus auctions, triggered on `vow.flap`.
+Implementations of MakerDAO surplus auctions, triggered on `vow.flap` or via new `kicker.flap`.
+
+### Kicker
+
+Implements a Splitter/Flapper calling function that replaces `Vow.flap` and can be called even when `Vat.dai(Vow) < Vat.sin(Vow)`.
+The triggering threshold is assumed to be carefully set up and controlled by governance, ensuring there is enough surplus secured (in the Vow based surplus buffer or elsewhere).
+
+Configurable Parameters:
+* `kbump` - Fixed lot size (`RAD` precision)
+* `khump` - Flap threshold (`RAD` precision, signed integer value).
+
+Note: It is assumed that the `Flop` auctions mechanism is disabled and remain in that state. As otherwise it could collide with the above mechanism.
+Currently this is done through the configuration of `Vow.sump` as max uint256 (aka infinity).
+
+Note 2: Rate limiting is ensured via the `Splitter`.
+
+Note 3: Stop functionality is implemented via the `Splitter.cage` function.
