 ``stats`` (dictionary)
 ~~~~~~~~~~~~~~~~~~~~~~
-* buckets
+``stats`` is a dictionary with only one field understood by warcprox,
+``"buckets"``. The value of ``"buckets"`` is a list of strings and/or
+dictionaries. A string signifies the name of the bucket; a dictionary is
+expected to have at least an item with key ``"bucket"`` whose value is the name
+of the bucket. The other currently recognized key is ``"tally-domains"``, which
+if supplied should be a list of domains. This instructs warcprox to
+additionally tally substats of the given bucket by domain. Host stats are
+stored in the stats table under the key
+``{parent-bucket}:{domain(normalized)}``, e.g. `"bucket2:foo.bar.com"` for the
+example below.
