-Environment setup
-=================
+Docker container setup
+======================
+
+To facilitate the setup of the Reinforced-lib and ns-3 connection, we provide a Dockerfile that contains all the necessary
+dependencies and configurations. You need to have Docker installed on your machine, which you can download from the
+`official website <https://www.docker.com/get-started>`_.
+
+To build the Docker image, use the Dockerfile `provided in the repository <https://github.com/m-wojnar/reinforced-lib/blob/main/examples/ns-3-ra/Dockerfile>`_.
+Navigate to the directory where the Dockerfile is located and run the following command ("rlib-ns3" is the name of the image):
+
+.. code-block:: bash
+
+    docker build -t "rlib-ns3" .
+
+Once the image is built, you can run the interactive session with the following command:
+
+.. code-block:: bash
+
+    docker run -it "rlib-ns3" bash
+
+To persist the changes made in the container, you can create a volume and mount it to the container by adding the ``-v``
+flag to the ``docker run`` command:
+
+.. code-block:: bash
+
+    docker volume create "rlib-ns3-data"
+    docker run -it -v "rlib-ns3-data:/home" "rlib-ns3" bash
+
+Reinforced-lib and ns-3 are already installed in the container, so you can proceed with the experiments described in the
+:ref:`simulation scenario section <Simulation scenario>`. The library is located in the ``/home/reinforced-lib`` directory and the
+ns-3 in the ``/home/ns-3-dev`` directory.
