## Docs

- [Introduction](https://www.ultracite.ai/docs): Learn what Ultracite is, which linting toolchains it supports, and how its zero-config presets help teams and AI write cleaner code.
- [Setup](https://www.ultracite.ai/docs/setup): Install Ultracite with your preferred package manager, choose the right presets, and generate editor and agent config for your project.
- [Configuration](https://www.ultracite.ai/docs/configuration): Understand Ultracite's default presets, how framework-specific layers work, and which overrides to keep when your project needs custom rules.
- [Usage](https://www.ultracite.ai/docs/usage): This section covers how to use Ultracite on a day-to-day basis — covering the command-line interface, editor integration details, and typical workflows.
- [Language Support](https://www.ultracite.ai/docs/languages): Compare language and file-format coverage across Biome, Oxlint, Oxfmt, ESLint, Prettier, and Stylelint to pick the toolchain that fits your project.
- [Monorepos](https://www.ultracite.ai/docs/monorepos): Use Ultracite in a monorepo with shared presets, workspace-aware config, and repo-wide editor defaults that stay consistent across packages.
- [Git Hooks](https://www.ultracite.ai/docs/git-hooks): Run Ultracite automatically before each commit with Husky, Lefthook, lint-staged, or pre-commit so staged files stay clean and consistent.
