+Installation Instructions
+*************************
+
+For Debian based GNU / Linux
+============================
+The following commands build qt5 and polarssl which are dependencies of the Software.
+For build dependencies please refer to the Qt documentation 
+( qtbase/src/plugins/platforms/xcb/README ). Polarssl needs cmake and build-essentials.
+
+    export YOURPREFIX=<Prefix of your choice (default /usr)>
+
+    curl https://download.qt-project.org/official_releases/qt/5.3/5.3.0/single/qt-everywhere-opensource-src-5.3.0.tar.xz.mirrorlist | grep SHA-256

+
+    sha256sum qt-everywhere-opensource-src-5.3.0.tar.xz
+
+    tar -xvmlf qt-everywhere-opensource-src-5.3.0.tar.xz
+
+    cd qt-everywhere-opensource-src-5.3.0/qtbase
+
+build dependencies have to to be installed at this point,
+see ../qtbase/src/plugins/platforms/xcb/README
+
+    ./configure --prefix=$YOURPREFIX \

+    -release  -nomake tests  -nomake examples  -confirm-license \

+    make install
+
+    curl -O https://polarssl.org/download/polarssl-1.3.7-gpl.tgz
+    6beef0281160bf07fefefd6b412dd1ce4c39261cf5300835aef442253f0400e5  polarssl-1.3.7-gpl.tgz
+
+    tar -xf polarssl-1.3.7-gpl.tgz
+    cd polarssl-1.3.7
+    mkdir build
+    cd build
+    cmake .. -DCMAKE_C_FLAGS=-fpic -DCMAKE_INSTALL_PREFIX=$YOURPREFIX
+    make && make test && make install
+
+To compile the software you can use plain cmake. An out of source build is
+highly suggested. For build options see CMakeList.txt
+
+    hg clone https://wald.intevation.org/hg/trustbridge/
+    cd trustbridge
+    mkdir build-linux
+    cd build-linux
+    cmake .. -DCMAKE_PREFIX_PATH=$YOURPREFIX
+
+
+For Microsoft Windows
+=====================
+The Windows variant can be cross compiled on Debian based GNU / Linux systems.
+The minimum requirement is debian stable.
+
+Dependencies on the Host system:
+    git autoconf automake bash bison bzip2 \
+    cmake flex gettext git g++ intltool \
+    libffi-dev libtool libltdl-dev libssl-dev \
+    libxml-parser-perl make openssl patch perl \
+    pkg-config scons sed unzip wget xz-utils autopoint \
+    gperf
+
+Build the windows:
+    MXEPATH=$YOURPREFIX/win
+    git clone https://github.com/mxe/mxe.git $MXEPATH
+    cd $MXEPATH
+    echo "MXE_TARGETS := i686-w64-mingw32.static" > settings.mk
+    make polarssl
+    make qtbase
+
+Workaround Qt CMake Bugs:
+    find $MXEPATH/usr/i686-w64-mingw32.static/qt5/lib/cmake -name \*.cmake | \
+        xargs sed -i 's/\/\([a-z]*\)\.lib/\/lib\1\.a/g'
+    sed -i 's/^_qt5gui_find_extra_libs.*//' \
+        $MXEPATH/usr/i686-w64-mingw32.static/qt5/lib/cmake/Qt5Gui/Qt5GuiConfigExtras.cmake
+
+Make an NSS build available in the MXE prefix:
+    # TODO -> Document how to build NSS,..
+    cp -r <magic nss folder> $MXEPATH/usr/i686-w64-mingw32.static/
+
+Compile the software:
+    cd trustbridge
+    mkdir build-windows
+    cd build-windows
+    MXETARGET=$MXEPATH/usr/i686-w64-mingw32.static/
+    cmake .. \
+        -DCMAKE_PREFIX_PATH="$MXETARGET/qt5;$MXETARGET;" \
+        -DNSS_INCLUDEDIR="/nss-3.12.7/include;/nss-3.12.7/public/nss" \
+        -DNSS_LIBDIR="/nss-3.12.7/lib" \
+        -DCMAKE_TOOLCHAIN_FILE="$MXETARGET/share/cmake/mxe-conf.cmake" \
+        -DCMAKE_VERBOSE_MAKEFILE=True
