+### Example
+
+```
+thor --amount 1000 --messages 100 ws://localhost:8080
+```
+
+This will hit the WebSocket server that runs on localhost:8080 with 1000
+connections and sends 100 messages over each established connection. Once `thor`
+is done with smashing your connections it will generate a detailed report:

+- Create all the concurrent/parallel connections.
+- Smash 1000 connections with the mighty Mjölnir.
