# Discovery
Discovery is the process of asking the server for its configuration.
You send the discovery HTTP request to the URL the user has
configured. If the user hasn't specified a path, use "/".
Then make a GET request to that URL with either Accept header set to
"text/x-camli-configuration" or the the URL query parameter
"camli.mode" set to "config":
GET /some/user/?camli.mode=config HTTP/1.1
Host: camlihost.example.com
Or:
GET / HTTP1.1
Host: 127.0.0.1
Accept: text/x-camli-configuration
The response is a JSON document:
