+1) Set up your own network at [https://my.zerotier.com/](https://my.zerotier.com/). For our example we'll just use the Earth network (8056c2e21c000001). Use its network id as follows:
 
-2) Place a blank network config file in the *netcon/docker-test* directory (e.g. "e5cd7a9e1c5311ab.conf")
+2) Generate two pairs of identity keys. Each public/private pair will be used by the *netcon* and *monitor* containers:
+    
+    ./zerotier-netcon-service -d -p8100 /tmp/netcon_first
+    ./zerotier-cli -D/tmp/netcon_first join 8056c2e21c000001

+    ./zerotier-cli -D/tmp/netcon_second join 8056c2e21c000001
+
+3) Copy the identity files to your *docker-test* directory. Names will be altered during copy step so the dockerfiles know which identities to use for each image/container: 
+
+    cp /tmp/netcon_first/identity.public docker-test/netcon_identity.public
+    cp /tmp/netcon_first/identity.private docker-test/netcon_identity.private

+4) Place a blank network config file in the *netcon/docker-test* directory (e.g. "8056c2e21c000001.conf")
