A pure API implementation *without*``telegram.ext`` is available as the standalone package ``python-telegram-bot-raw``. `See here for details. <https://github.com/python-telegram-bot/python-telegram-bot/blob/master/README_RAW.rst>`_
Note
----
Installing both ``python-telegram-bot`` and ``python-telegram-bot-raw`` in conjunction will result in undesired side-effects, so only install *one* of both.
The signatures are uploaded to both the `GitHub releases page <https://github.com/python-telegram-bot/python-telegram-bot/releases>`_ and the `PyPI project <https://pypi.org/project/python-telegram-bot/>`_ and end with a suffix ``.asc``.
Please find the public keys `here <https://github.com/python-telegram-bot/python-telegram-bot/tree/master/public_keys>`_.
The keys are named in the format ``<first_version>-<last_version>.gpg`` or ``<first_version>-current.gpg`` if the key is currently being used for new releases.
In addition, the GitHub release page also contains the sha1 hashes of the release files in the files with the suffix ``.sha1``.
This allows you to verify that a release file that you downloaded was indeed provided by the ``python-telegram-bot`` team.

Use this, if you want to use the ``telegram.ext.JobQueue``.
To install multiple optional dependencies, separate them by commas, e.g. ``pip install python-telegram-bot[socks,webhooks]``.
Additionally, two shortcuts are provided:
*``pip install python-telegram-bot[all]`` installs all optional dependencies.
*``pip install python-telegram-bot[ext]`` installs all optional dependencies that are related to ``telegram.ext``, i.e. ``[rate-limiter, webhooks, callback-data, job-queue]``.
Our Wiki contains an `Introduction to the API <https://github.com/python-telegram-bot/python-telegram-bot/wiki/Introduction-to-the-API>`_ explaining how the pure Bot API can be accessed via ``python-telegram-bot``.
Moreover, the `Tutorial: Your first Bot <https://github.com/python-telegram-bot/python-telegram-bot/wiki/Extensions-%E2%80%93-Your-first-Bot>`_ gives an introduction on how chatbots can be easily programmed with the help of the ``telegram.ext`` module.
It contains descriptions of all available classes, modules, methods and arguments as well as the `changelog <https://docs.python-telegram-bot.org/changelog.html>`_.
- The `wiki <https://github.com/python-telegram-bot/python-telegram-bot/wiki/>`_ is home to number of more elaborate introductions of the different features of ``python-telegram-bot`` and other useful resources that go beyond the technical documentation.
- Our `examples section <https://docs.python-telegram-bot.org/examples.html>`_ contains several examples that showcase the different features of both the Bot API and ``python-telegram-bot``.
1. We have a vibrant community of developers helping each other in our `Telegram group <https://telegram.me/pythontelegrambotgroup>`_. Join us! Asking a question here is often the quickest way to get a pointer in the right direction.
Please review our `contribution guidelines <https://github.com/python-telegram-bot/python-telegram-bot/blob/master/.github/CONTRIBUTING.rst>`_ to get started.
You can also help by `reporting bugs or feature requests <https://github.com/python-telegram-bot/python-telegram-bot/issues/new>`_.
Occasionally we are asked if we accept donations to support the development.
While we appreciate the thought, maintaining PTB is our hobby, and we have almost no running costs for it. We therefore have nothing set up to accept donations.
If you still want to donate, we kindly ask you to donate to another open source project/initiative of your choice instead.
