Hi. to setup nodes for the getting started guide, you need to execute the generate_sovrin_pool_transactions command. Here is an example:
su - sovrin -c "generate_sovrin_pool_transactions --nodes 4 --clients 4 --nodeNum $NODENUM --ips '10.20.32.201,10.20.32.202,10.20.32.203,10.20.32.204'"
You will need to replace the IP addresses with those of your validators.
Note: If this is for a node that will be part of the Alpha network that we are spinning up, this is not correct. In that case, you should have stopped short of actually starting your node up, and instead provided your information to Sovrin via form, so that you can be part of the genesis transaction pool.
