The Twilio Starter Kit for the Zend Framework is an open-sourced project by Michael Kimsal that provides a basic framework for integrating Twilio with the Zend Framework. The kit includes sample code to help developers understand how to integrate Twilio into their ZF projects, and it can be forked and contributed back to. The Twilio community has resources available for developers, including API reference documentation, SDKs, helper libraries, quickstarts, tutorials, ebooks, industry reports, webinars, and a developer community hub with best practices and inspiration.
