+-----------------------------------

+Docker can be used as a simple alternative to install **circtools**, taking care of all Python and R dependencies, thus making it well-suited for novice users. The only requirement is a working docker installation. The following command will install the latest stable version of **circtools**:
+
+.. code-block:: bash
+
+    docker pull jakobilab/circtools
+
+Subsequently, **circtools** can be run via
+
+.. code-block:: bash
+
+    docker run circtools [insert command args here]
+
+.. code-block:: bash
+
+Other than the additional command `docker run circtools` vs. just `circtools` all commands remain unchanged.

+Installation via GitHub
 --------------------------
 
 The GitHub installation will install the most recent version directly from the source repository. Use this method if you want the latest fixes and features.
