-- **For all other countries/regions: Starting from March 1st, 2024, please go to the [Gemini API](https://github.com/dsdanielpark/Gemini-API) package.**
-- For some countries/regions where the `__Secure-1PSID` cookie value ends with a single dot: [Bard API](https://github.com/dsdanielpark/Bard-API) >= 0.1.40
+A *unofficial* Python wrapper, [python-gemini-api](https://pypi.org/project/python-gemini-api/), operates through reverse-engineering, utilizing cookie values to interact with [Google Gemini](https://gemini.google.com) for users struggling with frequent authentication problems or unable to authenticate via [Google Authentication](https://developers.google.com/identity/protocols/oauth2?hl=en).

-Moving forward, updates will primarily focus on the Gemini API package. Alternatively, utilize the official Gemini API at [Google AI Studio](https://ai.google.dev/tutorials/ai-studio_quickstart).
