+## Helper Tasks In Dosh
+
+There is task runner called `dosh`.  Use `make bin/dosh` to add it to your
+document directory.  Then invoke dosh (or add that bin dir to your path with
+direnv or some such) with the name of the task you want to run. 
+
+`dosh watch` sets up an inotify hook to watch your latex file and run make when
+it changes.
+
+`dosh verify_pdf_links` tests the links in your PDF to see if they download
+properly.  This is useful mainly to make sure the sources we cite are addressed
+correctly.
+
+`bin/dosh` is just a bash script that calls `$OTS_DOCTOOLS/dosh`.  Feel free to
+add your own tasks or override the existing ones.
