Guides

Getting started Install the gem, set it up and add your first component. Build with AI Give coding agents the kit's context: llms.txt, docs/velvetkit.md and a Claude Code skill. Namespacing Put the components under any module, like Kit:: or Admin::. Theming and dark mode Colour tokens, corner radius and dark mode: retheme every component from one file. Lookbook Browse every preview, and run Lookbook in your app. Building forms Rails forms with VelvetKit: bind fields to a model, show its errors, and two live examples.
