+Installation
+============
+
+Before Suricata can be used it has to be installed. Suricata can be installed
+on various distributions using binary packages: :ref:`install-binary-packages`.
+
+For people familiar with compiling their own software, the Source method is
+recommended.
+
+Advanced users can check the advanced guides, see :ref:`install-advanced`.
+
+Source
+------
+
+Installing from the source distribution files gives the most control over the Suricata installation.
+
+Basic steps::
+
+    tar xzvf suricata-3.2beta1.tar.gz
+    cd suricata-3.2beta1
+    ./configure
+    make
+    make install
+
+This will install Suricata into ``/usr/local/bin/``, use the default
+configuration in ``/usr/local/etc/suricata/`` and will output to
+``/usr/local/var/log/suricata``
+
+
+Common configure options
+^^^^^^^^^^^^^^^^^^^^^^^^
+
+.. option:: --disable-gccmarch-native
+
+    Do not optimize the binary for the hardware it is built on. Add this 
+    flag if the binary is meant to be portable or if Suricata is to be used in a VM.
+
+.. option:: --prefix=/usr/
+
+    Installs the Suricata binary into /usr/bin/. Default ``/usr/local/``
+
+.. option:: --sysconfdir=/etc
+
+    Installs the Suricata configuration files into /etc/suricata/. Default ``/usr/local/etc/``
+
+.. option:: --localstatedir=/var
+
+    Setups Suricata for logging into /var/log/suricata/. Default ``/usr/local/var/log/suricata``
+
+.. option:: --enable-lua
+
+    Enables Lua support for detection and output.
+
+.. option:: --enable-geopip
+
+    Enables GeoIP support for detection.
+
+
