# Find the [httpd] section, uncomment the port
# and bind_address and set the bind_address to the IP of 
# your Pi to make couchDB accessible within your network

	[httpd]
	port = 5984
	bind_address = YOUR_IP_ADDRESS

# Example: 	bind_address = 192.168.0.211

# make couchdb user (created above) owner of local ini-file
