1. Remove your old fabric-tools / fabric-dev-servers (whatever you've called it) directory

2. mkdir ~/fabric-tools && cd ~/fabric-tools     #inside the directory

3. curl -O https://raw.githubusercontent.com/hyperledger/composer-tools/master/packages/fabric-dev-servers/fabric-dev-servers.tar.gz 

4. cd fabric-tools ; tar -xvf fabric-dev-servers.tar.gz

5. ./stopFabric.sh ; ./teardownFabric.sh ; ./fabric-tools/startFabric.sh
6. ./createPeerAdminCard.sh
7. cd ~/landreg-network/   # wherever your BNA file is etc

finally:

8. composer network install --card PeerAdmin@hlfv1 --archiveFile land-registry@0.0.1.bna

9. composer network start --networkName land-registry --networkVersion 0.0.1 --networkAdmin admin --networkAdminEnrollSecret adminpw --card PeerAdmin@hlfv1 --file networkadmin.card
