Development nodes are built, and can be started using ./rel/dev[123]/bin/bigcouch.\n\
Once the nodes are started, they must be joined together by editing the local\n\
nodes DB. For example, executing\n\
\n\
    curl localhost:15986/nodes/dev2@127.0.0.1 -X PUT -d '{}'\n\
    curl localhost:15986/nodes/dev3@127.0.0.1 -X PUT -d '{}'\n\
\n\
will cause node 1 to immediately connect to nodes 2 and 3 and form a cluster.\n\
The content of the nodes database is continuously replicated throughout the\n\
cluster, so this is a one-time operation.\n"
