 #### GENERAL NOTES
 
-See [sample Python script](https://github.com/tebelorg/RPA-Python/blob/master/sample.py), the [RPA Challenge solution](https://github.com/tebelorg/RPA-Python/issues/120#issuecomment-610518196), and [RedMart groceries example](https://github.com/tebelorg/RPA-Python/issues/24). To send a Telegram app notification, simply [look up @rpapybot](https://github.com/tebelorg/RPA-Python/issues/281#issue-942803794) to allow receiving messages. To automate Chrome browser invisibly, use [headless mode](https://github.com/tebelorg/RPA-Python/issues/240#issuecomment-839981773). To run 10X faster instead of normal human speed, use [turbo mode](https://github.com/tebelorg/RPA-Python/issues/297) (read the caveats!). Some CAPTCHAs can be solved using services like [2Captcha](https://2captcha.com), [Capsolver](https://www.capsolver.com) or directly by [replicating user actions](https://github.com/tebelorg/RPA-Python/issues/399#issuecomment-1163879428).

 [Securely share files](https://github.com/tebelorg/RPA-Python/issues/396#issuecomment-1169409452) up to 100 MB with built-in temporary online storage, on a dedicated [PrivateBin server](https://tebel.org/bin/). You can even run RPA on your phone browser [using this Colab notebook](https://colab.research.google.com/drive/1or8DtXZP8ZxJYK52me0dA6O9A1dXKKOE?usp=sharing) (eg datascraping with up to 5 Colab sessions). By design this package has [enterprise security](https://github.com/aisingapore/TagUI/blob/master/README.md#enterprise-security-by-design) and you can install, update and use it [without the internet](https://github.com/tebelorg/RPA-Python/issues/36#issuecomment-543670292).
