 The bootstrap script creates a simple setup with a faucet with 10 millions
 coins, a BFT leader, and a stake pool.
 
-It also creates 2 shell scripts parametrized to this specific
-run of bootstrap:
-
-* `faucet-send-money`
-* `faucet-send-certificate`
-
 Both scripts can be used to do simple limited operation through the jcli
 debugging tools.
