This tutorial is meant to get you up and running with ColdFusion and CouchDB. If you have never heard about CouchDB i suggest you read Matt Woodward's slighty chaotic but very informative article about CouchDB.
Step 1: Getting a CouchDB instance up and running
Currently (as of version 0.10) CouchDB is available for Linux and Mac. If you are running Linux, you might know how to get it up and running. If you got a Mac available (either your own or in your network) then things are very easy. Just download CouchDBX and you are ready to go in 1 minute.
After you started CouchDB you will see the administration interface called Futon. If you want to reach your CouchDB from another server, you will have to change the IP address on which CouchDB listens to requests:

Set the bind_address to 0.0.0.0 to make it listen to all requests or set it to the IP of that machine (e.g. 192.168.120.120) so it can only be reached within your network. If you leave it to the default (127.0.0.1) you will have a hard time reaching CouchDB through the network.
