+# CLAUDE.md
+
+This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
+
+## Project Overview
+
+cgithub is a lightweight GitHub alternative frontend that scrapes GitHub's server-rendered HTML instead of using the API. This approach avoids API rate limits entirely by extracting embedded JSON data from `<script type="application/json">` tags that GitHub includes for hydration.
+
+## Commands
+
+```bash
+# Development (watch mode with hot reload)
+pnpm run dev
+
+# Production build (bundles to dist/)
+pnpm run build
+
+# Deploy to production server
+make deploy
+```
+
+## Architecture
+
+**Stack:** Hono (web framework) + Eta (templating) + TypeScript, bundled with esbuild
+
+**Source files:**
+- `src/index.ts` - Hono routes and server setup (supports systemd socket activation via `LISTEN_FDS=1`)
+- `src/scraper.ts` - GitHub HTML fetching and JSON extraction logic
+
+**Templates:** `views/*.eta` - Eta templates with layout inheritance (`layout.eta` as base)
+
+**Routes:**
+- `GET /` - Home page
+- `GET /:owner/:repo` - Repository info with directory listing
+- `GET /:owner/:repo/tree/:branch/:path*` - Directory listing
+- `GET /:owner/:repo/blob/:branch/:path` - File content view
+
+**Scraper pattern:** GitHub embeds tree/blob data in two formats depending on page type:
+- `react-partial.embeddedData` (props.initialPayload) for root directories
+- `react-app.embeddedData` (payload) for subdirectories and blobs
+
+The scraper uses browser-like headers to avoid throttling.
