+### Precedence
+
+Nothing, of course, stops you from specifying multiple arguments in the query part of the URL, but only one will be used. The precedence is in this order:
+
+1. `docid` is considered first, and overrides anything else;
+2. `uri` is considered next, and overrides `file`;
+3. the value of `file` is considered only if neither of the other two are present.

 ## Not yet working
 
 GeoCSV is at an early stage of development, and some features are not yet working.
