                                                   #before the call to the setWebhook, so unwanted updates may be
                                                   #received for a short period of time.

           #'TIMEOUT':(Optional[int|float]), # If this value is specified,
                                   #use it as the read timeout from the server

           #'WEBHOOK_MAX_CONNECTIONS':(Optional[int]), # Maximum allowed number of
                                   #simultaneous HTTPS connections to the webhook for update

                                   #load on your bot's server, and higher values to increase your

                                   #|     0 - no retries (default)

           #'POLL_READ_LATENCY':(Optional[float|int]), # Grace time in seconds for receiving the reply from
                                   #server. Will be added to the `timeout` value and used as the read timeout from
                           #server (Default: 2).
        },
        #Other bots here with same structure.
    ],

}

Include in your urls.py the django_telegrambot.urls (NB: If you upgrade from a previous version, you MUST change how to include django_telegrambot.urls. Never set prefix here!):

#urls.py
urlpatterns = [
    ...
    url(r'^', include('django_telegrambot.urls')),
    ...
]

Then use it in a project creating a module telegrambot.py in your app

#myapp/telegrambot.py
# Example code for telegrambot.py module
from telegram.ext import CommandHandler, MessageHandler, Filters
from django_telegrambot.apps import DjangoTelegramBot

import logging
logger = logging.getLogger(__name__)


# Define a few command handlers. These usually take the two arguments bot and
# update. Error handlers also receive the raised TelegramError object in error.
def start(bot, update):
    bot.sendMessage(update.message.chat_id, text='Hi!')


def help(bot, update):
    bot.sendMessage(update.message.chat_id, text='Help!')


def echo(bot, update):
    bot.sendMessage(update.message.chat_id, text=update.message.text)


def error(bot, update, error):
    logger.warn('Update "%s" caused error "%s"' % (update, error))


def main():
    logger.info("Loading handlers for telegram bot")

    # Default dispatcher (this is related to the first bot in settings.DJANGO_TELEGRAMBOT['BOTS'])
    dp = DjangoTelegramBot.dispatcher
    # To get Dispatcher related to a specific bot
    # dp = DjangoTelegramBot.getDispatcher('BOT_n_token')     #get by bot token
    # dp = DjangoTelegramBot.getDispatcher('BOT_n_username')  #get by bot username

    # on different commands - answer in Telegram
    dp.add_handler(CommandHandler("start", start))
    dp.add_handler(CommandHandler("help", help))

    # on noncommand i.e message - echo the message on Telegram
    dp.add_handler(MessageHandler([Filters.text], echo))

    # log all errors
    dp.add_error_handler(error)
