 ```ruby
-  ws "/" do |socket|
+# Matches "/"
-    # Send welcome message to the client
+ws "/" do |socket|
-    socket.send "Hello from Kemal!"
+  # Send welcome message to the client
+  socket.send "Hello from Kemal!"
 
-    # Handle incoming message and echo back to the client
+  # Handle incoming message and echo back to the client
-    socket.on_message do |message|
+  socket.on_message do |message|
-      socket.send "Echo back from server #{message}"
+    socket.send "Echo back from server #{message}"
-    end

-    # Executes when the client is disconnected. You can do the cleaning up here.
-    socket.on_close do
