PostIt's time for Hacktoberfest again! 💻🥨

It's time for Hacktoberfest again! 💻🥨 Hacktoberfest is an event that encourages developers and everyone else to contribute to open source repositories. If you ever thought about starting coding or giving back to your favourite open source repositories, now is the time! Head over to the hacktoberfest website to learn more about it. This is also a great opportunity to contribute to python-telegram-bot 🙂 We have already prepared a few issues on our repositories, but feel free to begin a hunt for improvements and fixes by yourself! We'd like to especially point out issue #3109 and #3110, which are about improving our documentation. These issues can be tackled in multiple pull requests and are perfect for first time contributors. ⚠️ If you want to tackle an issue, please be sure to • leave a comment on the issue before you work on it, so that we can assign you. That way, we avoid duplicate pull requests for the same issue by several people. • read the contribution guide. For questions about making contributions to python-telegram-bot we also have a dedicated developer chat group, where you can get focused help if you run into problems while preparing your pull request.
