 Coordinator
 ~~~~~~~~~~~
 
-To start the coordinator, we will download the labgrid repository, create an
-extra virtualenv and install the dependencies:
+We can simply start the coordinator:
 
 .. code-block:: bash
 
-    $ sudo apt install libsnappy-dev
-    $ git clone https://github.com/labgrid-project/labgrid
-    $ cd labgrid
-    $ virtualenv -p python3 crossbar-venv
-    $ crossbar-venv/bin/pip install --upgrade pip
-    $ crossbar-venv/bin/pip install -r crossbar-requirements.txt
-    $ virtualenv -p python3 labgrid-venv
-    $ source labgrid-venv/bin/activate
-    labgrid-venv $ pip install --upgrade pip
-    labgrid-venv $ pip install .
-
-All necessary dependencies should be installed now.
-
-Copy and customize the crossbar config file ``.crossbar/config-anonymous.yaml``
-for your use case:
-
-.. code-block:: bash
-
-    labgrid-venv $ cp .crossbar/config-anonymous.yaml .crossbar/my-config.yaml
-
-.. note:: crossbar is a network messaging framework for building distributed
-          applications, which labgrid plugs into.
-
-The path to the Python interpreter in the labgrid-venv needs to be configured
-in crossbar's config, either manually or with the labgrid-venv being active
-via:
-
-.. code-block:: bash
-
-    labgrid-venv $ sed -i "s#^  executable: .*\$#  executable: ${VIRTUAL_ENV}/bin/python3#" .crossbar/my-config.yaml
-
-.. note:: For long running deployments a different ``workdir`` and port may be
-          used.
-          The crossbar config should reside in a ``.crossbar`` directory in the
-          ``workdir`` in this case.
-          For an example systemd service file, see
-          :ref:`remote-getting-started-systemd-files`.
-
-Now we can finally start the coordinator inside the repository:
-
-.. code-block:: bash
-
-    $ crossbar-venv/bin/crossbar start --config my-config.yaml
-
-.. note:: If --config is specified as a relative path, the config is expected
-          in a .crossbar subdirectory (as is the case in the labgrid
-          repository).
