How to run "byfn.sh generate" to Generate BYFN Network Configuration?

You can follow this tutorial to run "byfn.sh generate" to Generate BYFN Network Configuration with default values.

The "./byfn.sh generate" command automatically calls: "../bin/cryptogen" to generate certificates, and "../bin/configtxgen" to generate the Genesis block,

$ cd hyperledger-binaries/fabric-samples/first-network
 
$ ./byfn.sh generate

Generating certs and genesis block for channel 'mychannel' with CLI 
timeout of '10' seconds and CLI delay of '3' seconds

Continue? [Y/n] y
proceeding ...

As you can see, our default network will have 2 organizations "Org1" and "Org2" with 1 channel "mychannel".
