This is the old message:

To start the nodes, in separate terminals use:
 
cardano-node run \
  --config                          example/configuration.yaml \

This is the new message:

To start the nodes, in separate terminals use:

example/run/node-bft1.sh
example/run/node-bft2.sh
example/run/node-pool1.sh

Alternatively, you can run all the nodes in one go:

example/run/all.sh
