+Prerequisites
+-------------
+
+Virtualisation provider
+~~~~~~~~~~~~~~~~~~~~~~~
+
+Environment has been tested using libvirt_ provider with vagrant-libvirt_ plugin. Plugin
+documentation provides detailed `installation instructions`_ that will guide through the process.
+
+.. note::
+   Remember to uncomment `deb-src` repositories for `apt-get build-dep` step on Debian/Ubuntu.

+
+Virtual machine manager
+~~~~~~~~~~~~~~~~~~~~~~~
+
+Environment has been tested using latest Vagrant_ as of writing this documentation (`v2.2.6`_). Some
+features (e.g. triggers_) might not be supported on older versions.
+
+.. _Vagrant: https://www.vagrantup.com/downloads.html
+.. _`v2.2.6`: https://github.com/hashicorp/vagrant/blob/v2.2.6/CHANGELOG.md#226-october-14-2019
+.. _triggers: https://www.vagrantup.com/docs/triggers/
+
+
+Running
+-------
+
+Additional `--provider` flag or setting `VAGRANT_DEFAULT_PROVIDER` environmental variable might be
+useful in case there are multiple providers available.
+
+.. note::
+   Following command should be executed within the directory where `Vagrantfile` is stored
+   (`integration/bootstrap/codesearch`).
+
+.. code-block:: sh
+   vagrant up --provider=libvirt
+
+This will:
+
+#. Start and prepare virtual machine
+#. Generate required authorization and configuration files
+#. Run Hound instance as a tmux_ session named `codesearch`
+
+.. _tmux: https://github.com/tmux/tmux/wiki
+
+
+Usage
+-----
+
+Once ready (cloning repositories and building index might initially take some time) code search will
+be available at http://localhost:6080
