+At its core design, `DUNE` is able to configure and leverage `mpf` to deploy the emulated infrastructure.
+
+```python
+#! /usr/bin/ipython
 
-## Quick Start
+import dune
+from dune import mpf
 
-DUNE requires two main files: (i) infra.yml and (ii) topo.yml.
-The first one describes the physical infrastructure used for the emulation.
-It can range from a single server to a cluster.
-The second one describes the topology to emulate.
+dune.init("topology.toml")
 
-See [infra.sample.yml](infra.sample.yml) and [topo.sample.yml](topo.sample.yml) for illustration.
