+=============
+
+To install the complete :ref:`searx suite (includes searx, morty & filtron)

+
+  $ sudo -H ./utils/lxc.sh install suite

+command.  To test instances from containers just open the URLs in your

+
+  $ sudo ./utils/lxc.sh show suite | grep filtron

+Running commands
+================
+
+**Inside containers, you can use make or run scripts** from the
+:ref:`toolboxing`.  By example: to setup a :ref:`buildhosts` and run the
+Makefile target ``test`` in the archlinux_ container::
+
+  sudo -H ./utils/lxc.sh cmd searx-archlinux ./utils/searx.sh buildhost
+  sudo -H ./utils/lxc.sh cmd searx-archlinux make test

+
+Setup searx buildhost
+=====================
+
+You can **install the searx buildhost environment** into one or all containers.
+The installation procedure to set up a :ref:`build host<buildhosts>` takes its
+time.  Installation in all containers will take more time (time for another cup
+of coffee).::
+
+  sudo -H ./utils/lxc.sh cmd -- ./utils/searx.sh buildhost
+
+To build (live) documentation inside a archlinux_ container::
+
+  sudo -H ./utils/lxc.sh cmd searx-archlinux make docs-clean docs-live
