-It is strongly advised that you read the source code for the [`InteractiveTelegramClient`](https://github.com/LonamiWebs/Telethon/blob/master/telethon_examples/interactive_telegram_client.py) for an overview on how you could build your next script. This example shows a basic usage more than enough in most cases. Even reading the source for the [`TelegramClient`](https://github.com/LonamiWebs/Telethon/blob/master/telethon/telegram_client.py) may help a lot!

 ## Common steps
 
-All examples listed here assume that you have successfully created a client and you're authorized as follows:
-
-```python
-from telethon import TelegramClient
-
-# Use your own values here
-api_id = 12345
-api_hash = '0123456789abcdef0123456789abcdef'
-phone_number = '+34600000000'
-
-client = TelegramClient('some_name', api_id, api_hash)
-client.connect()  # Must return True, otherwise, try again
-
-if not client.is_user_authorized():
-    client.send_code_request(phone_number)
-    # .sign_in() may raise PhoneNumberUnoccupiedError
-    # In that case, you need to call .sign_up() to get a new account
-    client.sign_in(phone_number, input('Enter code: '))
-
-# The `client´ is now ready
-```
-
-Although Python will probably clean up the resources used by the `TelegramClient`, you should always `.disconnect()` it once you're done:
-```python
-try:
-    # Code using the client goes here
-except:
-    # No matter what happens, always disconnect in the end
-    client.disconnect()
-```
