 ## Configuration
 
-* creates a little TCL shim that tells OpenLane where the source is and the name of the top module
+* creates a little TCL shim that tells LibreLane where the source is and the name of the top module
 * makes sure the top module is not called 'top'
-* if you have OpenLane installed locally, then you can harden the design with --harden
