+Socket.IO Tornado Examples
+==========================
+
+This directory contains example Socket.IO applications that are compatible
+with the Tornado framework. These applications require Tornado 5 and Python
+3.5 or later.
+
+app.py
+------
+
+A basic "kitchen sink" type application that allows the user to experiment
+with most of the available features of the Socket.IO server.
+
+latency.py
+----------
+
+A port of the latency application included in the official Engine.IO
+Javascript server. In this application the client sends *ping* messages to
+the server, which are responded by the server with a *pong*. The client
+measures the time it takes for each of these exchanges and plots these in real
+time to the page.
+
+This is an ideal application to measure the performance of the different
+asynchronous modes supported by the Socket.IO server.
+
+Running the Examples
+--------------------
+
+To run these examples, create a virtual environment, install the requirements
+and then run::
+
+    $ python app.py
+
+or::
+
+    $ python latency.py
+
+You can then access the application from your web browser at
+``http://localhost:8888``.
