 ## How to run
 
+First make sure that simulaqron is started with the nodes you'd want to include.
+This can be done with for example `simulaqron start` which by default starts a network
+with the nodes Alice, Bob, Charlie, David and Eve.
+Note that you need to be using either the qutip or projectq backend, since single-qubit
+rotations are used which are not supported in stabilizer formalism.
+To change the backend do `simulaqron set backend projectq`, which of course requires projectq
+to be installed (`pip install projectq`).
+
+In this folder there is both an example with the four nodes Alice, Bob, Charlie and David
+and one where you can dynamically choose the nodes that the example uses.
+
+To start either of the examples do
+```
+python3 fourPartyCoinFlip.py
+```
+or
 ```
-sh $NETSIM/run/startAll.sh
-./run.sh
+python3 nPartyCoinFlip.py
 ```
 
-Note that you need to give the nodes a few seconds to start up after running
-the first command.
+When running `nPartyCoinFlip.py` fill in the names you want to use (note that these needs to 
+be in the current running network) and press enter when you're finished.
