+# Repository guidelines
+
+## Project structure & module organization
+
+- Monorepo via `pnpm` + `Nx`.
+- Packages: `packages/core` (CLI + `@rspress/core`), `packages/theme-default` (Default theme), `packages/plugin-*` (Official plugins), `packages/create-rspress` (scaffolder).
+- Tests: `packages/*/tests` (unit) and `e2e/` (end-to-end tests); website examples in `website/`.
+- Key config: `nx.json`, `biome.json`, `.prettierrc`, `playwright.config.ts`, `pnpm-workspace.yaml`.
+
+## Build, test, and development commands
+
+- Install: `pnpm install` (Node >= 18.0, pnpm >= 10.15).
+- Build: `pnpm build` (all) and `pnpm build:website`.
+- Watch dev: `pnpm dev` (all packages) or `pnpm dev:website` (documentation site).
+- Lint/format: `pnpm lint`; auto-fix: `pnpm format`.
+- Tests: `pnpm test`; targeted: `pnpm test:unit` or `pnpm test:e2e`; update snapshots: `pnpm testu`.
+
+## Coding style & naming conventions
+
+- TypeScript + ESM; spaces; single quotes.
+- Biome is canonical linter/formatter; Prettier formats MD/CSS/JSON and `package.json`.
+- Filenames: `camelCase` or `PascalCase` (Biome enforced).
+
+## Testing guidelines
+
+- Unit: `vitest`; E2E: `@playwright/test`.
+- Naming: `*.test.ts`/`*.test.tsx`; snapshots in `__snapshots__/`.
+- Placement: unit under `packages/*/tests`; e2e under `e2e/`.
+
+## Commit & pull request guidelines
+
+- Conventional Commits (e.g., `feat(plugin-algolia): ...`); keep commits focused; run lint + tests.
+- User-facing changes need a Changeset (`pnpm changeset`); PRs should include description, linked issues, and doc/example updates when needed.
+
+## Architecture overview
+
+- `packages/core` (`@rspress/core`): CLI `rspress build/dev` (add `--watch`), config via `rspress.config.ts` using `defineConfig`; programmatic `import { defineConfig, loadConfig } from '@rspress/core'`.
+- `packages/theme-default` (`@rspress/theme-default`): Default theme with components and layouts.
+- `packages/plugin-*` (`@rspress/plugin-*`): Official plugins like `plugin-algolia` (search), `plugin-llms` (LLM optimization), `plugin-typedoc` (API docs), etc.
+- `packages/create-rspress` (`create-rspress`): scaffold new projects/templates with `pnpm dlx create-rspress` (or `npx create-rspress`).
+
+## Security & configuration tips
+
+- Do not commit build artifacts (`dist/`, `compiled/`).
+- Nx caching is enabled; scripts use `NX_DAEMON=false` for reproducible CI.
