+Test Servers
+============
+
+If you wish to test your application in a separate environment, Pyrogram is able to authorize your account into
+Telegram's test servers without hassle. All you need to do is start a new session (e.g.: "my_account_test") using
+``test_mode=True``:
+
+.. code-block:: python
+
+    from pyrogram import Client
+
+    with Client("my_account_test", test_mode=True) as app:
+        print(app.get_me())
+
+.. note::
+
+    If this is the first time you login into test servers, you will be asked to register your account first.
+    Don't worry about your contacts and chats, they will be kept untouched inside the production environment;
+    accounts authorized on test servers reside in a different, parallel instance of a Telegram database.
+
+Test Mode in Official Apps
+--------------------------
+
+You can also login yourself into test servers using official desktop apps, such as Webogram and TDesktop:
+
+- **Webogram**: Login here: https://web.telegram.org/?test=1
+- **TDesktop**: Open settings and type ``testmode``.
+
+Test Numbers
+------------
+
+Beside normal numbers, the test environment allows you to login with reserved test numbers.
+Valid phone numbers follow the pattern ``99966XYYYY``, where ``X`` is the DC number (1 to 3) and ``YYYY`` are random
+numbers. Users with such numbers always get ``XXXXX`` as the confirmation code (the DC number, repeated five times).
+
+.. important::
+
+    Do not store any important or private information in such test users' accounts; anyone can make use of the
+    simplified authorization mechanism and login at any time.
