The text discusses the importance of having effective quick start guides in API documentation to facilitate experiential learning, which is favored by developers who prefer learning-by-doing. These guides aim to demonstrate the simplest API functions with minimal steps, making them accessible and appealing to developers. Different approaches to creating quick start guides include using language-agnostic commands like curl or Postman to allow immediate testing without setup, and providing SDKs or sample projects to shorten the time to first “hello world” (TTFHW). The text highlights examples from companies like GitHub, Mailgun, Square, Clearbit, Dropbox, Parse, and Auth0, illustrating how each effectively engages developers with their APIs. These guides not only lower the barrier to entry for developers but also serve as essential marketing tools by demonstrating the API's utility and ease of use, thus encouraging further exploration and integration.
