+The optional `among` parameter limits the pages whose outgoing links are
+considered. For instance, to display a cloud of tags used on blog
+entries, while ignoring other pages that use those tags, you could use:
+
+ \[[!pagestats pages="tags/*" among="blog/posts/*"]]
+
+Or to display a cloud of tags related to Linux, you could use:
+
+ \[[!pagestats pages="tags/* and not tags/linux" among="tagged(linux)"]]
+
+The optional `show` parameter limits display to the specified number of
+pages. For instance, to show a table of the top ten pages with the most
+links:
+
+ \[[!pagestats style="table" show="10"]]
+
+The optional `class` parameter can be used to control the class
+of the generated tag cloud `div` or page stats `table`.
