+Composable [oxlint](https://oxc.rs/docs/guide/usage/linter.html) configuration presets.
+
+## Install
+
+```bash
+pnpm install -D @robonen/oxlint oxlint
+```
+
+## Usage
+
+Create `oxlint.config.ts` in your project root:
+
+```ts
+import { defineConfig } from 'oxlint';
+import { compose, base, typescript, vue, vitest, imports } from '@robonen/oxlint';
+
+export default defineConfig(
+  compose(base, typescript, vue, vitest, imports),
+);
+```
+
+Append custom rules after presets to override them:
+
+```ts
+compose(base, typescript, {
+  rules: { 'eslint/no-console': 'off' },
+  ignorePatterns: ['dist'],
+});
+```
+
+## Presets
+
+| Preset       | Description                                        |
+| ------------ | -------------------------------------------------- |
+| `base`       | Core eslint, oxc, unicorn rules                    |
+| `typescript` | TypeScript-specific rules (via overrides)           |
+| `vue`        | Vue 3 Composition API / `<script setup>` rules     |
+| `vitest`     | Test file rules (via overrides)                    |
+| `imports`    | Import rules (cycles, duplicates, ordering)        |
+| `node`       | Node.js-specific rules                             |
+
+## API
+
+### `compose(...configs: OxlintConfig[]): OxlintConfig`
+
+Merges multiple configs into one:
+
+- **plugins** — union (deduplicated)
+- **rules / categories** — last wins
+- **overrides / ignorePatterns** — concatenated
+- **env / globals** — shallow merge
+- **settings** — deep merge
