+Installation Prerequisites
+==========================
+You already should have installed and configured Postfix and Dovecot with
+PostgreSQL support. You also need access to a local or remote PostgreSQL
+server.
+
+To verify that your Dovecot and Postfix installation has support for
+PostgreSQL use the ``postconf`` and ``dovecot`` commands as shown below::
+
+        hostname ~ # postconf -m | grep pgsql
+        pgsql
+        hostname ~ # postconf -a | grep dovecot
+        dovecot
+        hostname ~ # dovecot --build-options | grep postgresql
+        SQL drivers: mysql postgresql sqlite
+
+vmm depends on Python (≥ 2.4.0) and Psycopg_ (≥ 2.0) or pyPgSQL_ (≥ 2.5.1).
+Psycopg and pyPgSQL are depending on parts of the *eGenix.com mx Base
+Distribution* (mxDateTime_ and mxTools_).
+
+If you are using Python ≤ 2.5.0:
+
+  • if you want to store your users' passwords as ``PLAIN-MD4`` digest in the
+    database, vmm will try to use ``Crypto.Hash.MD4`` from PyCrypto_
+  • if you are using Dovecot ≥ v1.1.0 and you want to store your users'
+    passwords as ``SHA256`` or ``SSHA256`` hashes, vmm will try to use
+    ``Crypto.Hash.SHA256`` from PyCrypto. For ``SHA256``/``SSHA256`` you
+    should have installed PyCrypto, at least in version 2.1.0alpha1.
+
+  When the Crypto.Hash module couldn't be imported, vmm will use
+  dovecotpw/doveadm, if  the *misc.password_scheme* setting in your *vmm.cfg*
+  is set to ``PLAIN-MD4``, ``SHA256`` or ``SSHA256``.
