+Requirements
+------------
+
+* You need Qt 4.2 or higher to build Psi. If a packaged version of Qt is not
+available for your OS (or if you want debug symbols in your Qt libraries), you
+will need to build and install Qt 4.1 yourself. See the Qt instructions to find
+out how to do this.
+
+* You need QCA 2.0 and the QCA OpenSSL plugin, which you can get at
+		http://delta.affinix.com/qca/2.0/beta2
+Instructions on how to build these packages can be found below. 
+
+The 'Building QCA' and 'Building QCA the OpenSSL plugin' sections can be 
+skipped by downloading the sources of these packages, and unpackaging them
+in third-party/qca (see the INSTALL file for the exact location of each
+package).
+
+
+Building QCA
+------------
+
+After unpacking the QCA sources, run the following command:
+
+ ./configure --prefix=/usr/local/qca2
+
+If configure cannot find your Qt4 library, use the --qtdir option to specify
+the path to Qt (e.g. /usr/share/qt4), or make sure that the qmake binary for
+Qt4 occurs first in your PATH. If something else goes wrong, use the --debug
+option to get more information on the configuration process.
+
+After QCA configured, run
+
+ make
+ make install
+
+To be able to run applications using QCA2, you will need to add
+/usr/local/qca2/lib to /etc/ld.so.conf and run ldconfig, or add
+/usr/local/qca2/lib to your LD_LIBRARY_PATH.
+
+
+
+Building the QCA OpenSSL plugin
+-------------------------------
+After unpacking the QCA OpenSSL plugin's sources, run the following commands
+
+ ./configure
+ make
+ make install
+
+See above on how to troubleshoot configure problems.
+
+
+
+Building the QCA GnuPG plugin
+-------------------------------
+After unpacking the QCA GnuPG plugin's sources, run the following commands
+
+ ./configure
+ make
+ make install
+
+See above on how to troubleshoot configure problems.
+
+
+Building Psi
+------------
+
+From the toplevel Psi source dir, run the following commands:
+
+ ./configure --prefix=/usr/local/psi
+ make
+ make install
+
+This should configure, build, and install Psi. See above on how to troubleshoot 
+configure problems.
