-Transforms for computing the arithmetic mean of the elements in a collection,
-or the mean of the values associated with each key in a collection of key-value pairs.</p>
+<p><br /></p>
+
+<p>Estimates the number of distinct elements in a data stream using the
+<a href="http://static.googleusercontent.com/media/research.google.com/en/us/pubs/archive/40671.pdf">HyperLogLog++ algorithm</a>.
+The respective transforms to create and merge sketches, and to extract from them, are:</p>
 
 <ul>
-  <li><code class="highlighter-rouge">Mean.globally()</code> returns a transform that then returns a collection whose contents is the mean of the input collection’s elements. If there are no elements in the input collection, it returns 0.</li>
-  <li><code class="highlighter-rouge">Mean.perKey()</code> returns a transform that returns a collection that contains an output element mapping each distinct key in the input collection to the mean of the values associated with that key in the input collection.</li>
+  <li><code class="highlighter-rouge">HllCount.Init</code> aggregates inputs into HLL++ sketches.</li>
+  <li><code class="highlighter-rouge">HllCount.MergePartial</code> merges HLL++ sketches into a new sketch.</li>
+  <li><code class="highlighter-rouge">HllCount.Extract</code> extracts the estimated count of distinct elements from HLL++ sketches.</li>
 </ul>
