## What it is
A Ruby gem that integrates the Tailwind CSS utility-first framework into Rails applications, bundling the standalone tailwindcss executable and providing Rails tasks for building and watching styles. It supports Rails 7+ installation generators, live rebuilds, production asset precompilation, and Tailwind v4 upgrades.

## Use cases
- add tailwind css to a rails app
- build tailwind styles in rails asset pipeline
- watch and rebuild css during rails development
- precompile tailwind css for production in rails
- upgrade rails app from tailwind v3 to v4
- use tailwind with rails engines

## When to choose
- you're building a Rails 7+ app and want Tailwind CSS without a Node toolchain
- you want an officially maintained Rails integration with install generators and rake tasks
- you need live CSS rebuilding during development and simple production precompilation

## When to avoid
- you're not using Ruby on Rails
- you need heavy customization via PostCSS plugins or a full Node-based build pipeline
- you use a different CSS framework or prefer plain CSS/Sass
