+       Xapian 1.1.4 (or later). Previous versions of Xapian (whether
+       1.0 or 1.1) had a performance bug that made notmuch very slow
+       when modifying tags. This would cause distracting pauses when
+       reading mail while notmuch would wait for Xapian when removing
+       the "inbox" and "unread" tags from messages in a thread.

+       ----------
+       GMime provides decoding of MIME email messages for Notmuch.
 
        Without GMime, Notmuch would not be able to extract and index

+Building Documentation
+----------------------
+
+To build the documentation for notmuch you need at least version 1.0
+of sphinx (Jul. 2010).
+
+Sphinx is available from www.sphinx-doc.org.
 
+Installing Dependencies from Packages
+-------------------------------------
+
+On a modern, package-based operating system you can install all of the
+dependencies with a simple simple command line. For example:
+
+  For Debian and similar:
+
+        sudo apt-get install libxapian-dev libgmime-2.6-dev libtalloc-dev zlib1g-dev python-sphinx
+
+  For Fedora and similar:
+
+       sudo yum install xapian-core-devel gmime-devel libtalloc-devel zlib-devel python-sphinx
+
+On other systems, a similar command can be used, but the details of
+the package names may be different.
