+# Next.js + Claude Code + Codex
+
+Production-ready Next.js 14 app with integrated Claude Code Client([Happy](https://github.com/slopus/happy)).
+
+## Setup
+
+### 1. Configure Claude Code API Key
+
+Before using Claude Code, set your API token:
+
+```bash
+# Set the token for current session
+export ANTHROPIC_AUTH_TOKEN=your_token_here
+
+# Make it persistent (survives restarts)
+echo 'export ANTHROPIC_AUTH_TOKEN=your_token_here' >> ~/.bashrc
+source ~/.bashrc
+```
+
+**Getting your token:**
+1. Open **AI Proxy** application in [Sealos](https://os.sealos.io)
+2. Click **API Keys** in the left sidebar
+3. Click **+New** to create a new API key
+4. Copy the generated token
+
+### 2. Download Mobile App
+
+- **iPhone/iPad**: [App Store ](https://apps.apple.com/us/app/happy-claude-code-client/id6748571505)
+- **Android**: [Google Play ](https://play.google.com/store/apps/details?id=com.ex3ndr.happy)
+- **Web App**: [app.happy.engineering ](https://app.happy.engineering)
+
+### 3. Scan the QR code with your mobile app
+
+```bash
+happy --auth # Shows QR code

+
+Once you’ve connected your mobile app to your DevBox runtime.
