+ zlib
+ ----
+
+ zlib is an extremely popular compression library. It is used
+ by Xapian, so if you installed that you will already have
+ zlib. You may need to install the zlib headers separately.
+
+ Notmuch needs the transparent write feature of zlib introduced
+ in version 1.2.5.2 (Dec. 2011).
+
+ zlib is available from http://zlib.net
+
+Building Documentation
+----------------------
+
+By default the documentation for notmuch is built using sphinx.
+
+Sphinx is available from www.sphinx-doc.org.
+
+If you prefer, you can build the man pages using rst2man, from the
+python docutils package. See doc/INSTALL for details.
