+== Building Debian packages ==
+
+Instead of creating a personal installation as in the previous step you can
+also create debian package.  This is done from the qgis root directory, where
+you'll find a debian directory.
+
+First you need to install the debian packaging tools once:
+
+```
+apt-get install build-essential
+```
+
+The QGIS packages will be created with:
+
+```
+dpkg-buildpackage -us -us -b
+```
+
+/!\ ***Note:*** If ``dpkg-buildpackage`` complains about unmet build dependencies
+you can install them using ``apt-get`` and re-run the command.
+
+/!\ ***Note:*** If you have ``libqgis1-dev`` installed, you need to remove it first
+using ``dpkg -r libqgis1-dev``.  Otherwise ``dpkg-buildpackage`` will complain about at
+build conflict.
+
+The the packages are created in the parent directory (ie. one level up).
+Install them using dpkg.  E.g.:
+
+```
+sudo dpkg -i \
+	../qgis_1.0preview16_amd64.deb \
+	../libqgis-gui1_1.0preview16_amd64.deb \
