+This example demonstrates an advanced federated learning setup using Flower with TensorFlow/Keras. This example uses [Flower Datasets](https://flower.dev/docs/datasets/) and it differs from the quickstart example in the following ways:
 
 - 10 clients (instead of just 2)
 - Each client holds a local dataset of 1/10 of the train datasets and 80% is training examples and 20% as test examples (note that by default only a small subset of this data is used when running the `run.sh` script)

 ## Run Federated Learning with TensorFlow/Keras and Flower
 
-The included `run.sh` will call a script to generate certificates (which will be used by server and clients), start the Flower server (using `server.py`), sleep for 2 seconds to ensure the the server is up, and then start 10 Flower clients (using `client.py`). You can simply start everything in a terminal as follows:

You can simply start everything in a terminal as follows:
 
 ```shell

+# Once you have activated your environment
+./run.sh
 ```
 
 The `run.sh` script starts processes in the background so that you don't have to open eleven terminal windows. If you experiment with the code example and something goes wrong, simply using `CTRL + C` on Linux (or `CMD + C` on macOS) wouldn't normally kill all these processes, which is why the script ends with `trap "trap - SIGTERM && kill -- -$$" SIGINT SIGTERM EXIT` and `wait`. This simply allows you to stop the experiment using `CTRL + C` (or `CMD + C`). If you change the script and anything goes wrong you can still use `killall python` (or `killall python3`) to kill all background processes (or a more specific command if you have other Python processes running that you don't want to kill).
