+This example explains how to run the Krum fusion algorithm to train CNNs implemented with Keras training
 on [MNIST](http://yann.lecun.com/exdb/mnist/) data. Data in this example preprocessed by scaling down to range from `[0, 255]` to `[0, 1]`.
 No other preprocessing is performed.
 
+**Note that** the parameter `byzantine_threshold` is set to `1` by default. According to Krum's assumption, the number of parties in the FL system should be at least `2 * byzantine_threshold + 3`. Therefore, to run this example, please create at least `5` parties.
