+# CI Environment Support
+
+Automatically detect CI environments and toggle features based on local vs CI builds.
+
+## Overview
+
+tsdown uses the [`is-in-ci`](https://www.npmjs.com/package/is-in-ci) package to detect CI environments. This covers GitHub Actions, GitLab CI, Jenkins, CircleCI, Travis CI, and more.
+
+## CI-Aware Values
+
+Several options accept CI-aware string values:
+
+| Value | Behavior |
+|-------|----------|
+| `true` | Always enabled |
+| `false` | Always disabled |
+| `'ci-only'` | Enabled only in CI, disabled locally |
+| `'local-only'` | Enabled only locally, disabled in CI |
+
+## Supported Options
+
+These options accept CI-aware values:
+
+- `dts` - TypeScript declaration file generation
+- `publint` - Package lint validation
+- `attw` - "Are the types wrong" validation
+- `report` - Bundle size reporting
+- `exports` - Auto-generate `package.json` exports
+- `unused` - Unused dependency check
+- `devtools` - DevTools integration
+- `failOnWarn` - Fail on warnings (defaults to `'ci-only'`)
+
+## Usage
+
+### String Form
+
+```ts
+export default defineConfig({
+  dts: 'local-only',        // Skip DTS in CI for faster builds
+  publint: 'ci-only',       // Only run publint in CI
+  failOnWarn: 'ci-only',    // Fail on warnings in CI only (default)
+})
+```
+
+### Object Form
+
+When an option takes a configuration object, set `enabled` to a CI-aware value:
+
+```ts
+export default defineConfig({
+  publint: {
+    enabled: 'ci-only',
+    level: 'error',
+  },
+  attw: {
+    enabled: 'ci-only',
+    profile: 'node16',
+  },
+})
+```
+
+### Config Function
+
+The config function receives a `ci` boolean in its context:
+
+```ts
+export default defineConfig((_, { ci }) => ({
+  minify: ci,
+  sourcemap: !ci,
+}))
+```
+
+## Typical CI Configuration
+
+```ts
+export default defineConfig({
+  entry: 'src/index.ts',
+  format: ['esm', 'cjs'],
+  dts: true,
+  failOnWarn: 'ci-only',
+  publint: 'ci-only',
+  attw: 'ci-only',
+})
+```
