The Alpaca documentation site has been improved to provide a more seamless and interactive experience for users. The new features include "Suggest Edits," which allows any user to contribute to the accuracy and clarity of the content, as well as live API interaction, which enables users to test and experiment with APIs directly within the documentation in real-time. This upgrade supports over 18 programming languages and provides a hands-on experience for developers to learn and build robust applications using Alpaca's APIs. The site also includes a survey to gather feedback from users and contact information for any questions or concerns.
