 # Description
 Implements some basic automation for auto submitting tips on [kicktipp](https://kicktipp.com). The auto submitting is based on [selenium](https://www.selenium.dev) browser automation. Login credentials are PGP-encrypted with [SOPS](https://technotim.live/posts/install-mozilla-sops/).
 
-Currently only result submitting for the `2-1 bot` is implemented, but the automation module can be extended easily for each types of bets.
+Currently only two result submitting strategies are implemented:
+- `2-1` for the "2-1 bot" (use -2, default)
+- `random` for the "random bot" (use -r)
+
+but the automation module can be extended easily to support any type of bets.
