[MalekLahbib]

Description: After trying the tutorial, here's my modification suggestions:

• Specify to execute make fclean; go run ./cmd/gnoland start in gno.land folder

• Delete the gnofaucet part, and suggest to modify the genesis_balances.txt file instead.

• in the end, change:
  After inserting your package path,... visit https://test3.<your_realm_path>.
  to :
  After inserting your package path, ... visit https://test3.gno.land/<your_realm_path> (Ex: https://test3.gno.land/r/leon/whitelistfactory).
