# FABA > For Agents, By Agents. Build software for agents. Build it with agents. FABA argues that agents should be users and builders of software. People choose their agent. Software should expose the whole product to that agent. Agents' experience should shape the tools they use. ## Manifesto - [Manifesto in Markdown](./manifesto.md): The complete FABA manifesto. - [Manifesto in HTML](./faba.html): The same text with the site's visual design. ## Sweatshirts - [Buy a FABA sweatshirt](./buy.md): Live product catalog, size measurements, checkout URL format, shipping, payment, and returns.
