-## Highlights
+## ⭐ If You Find It Useful, Please Give It a Star!
 
-- **Claude Code protocol compatibility**: `thoughtSignature` fallback + cache, tool_result passthrough, and message ordering fixes.
-- **Antigravity OAuth**: account type `gemini-antigravity` with permission checks.
-- **Path-based routing (Anthropic Messages API)**:
-  - `/api` -> Claude account pool (default)
-  - `/antigravity/api` -> Antigravity OAuth account pool
-  - `/gemini-cli/api` -> Gemini OAuth account pool
-- **Stability**:
-  - Zombie stream watchdog (disconnect after 45s without valid data)
-  - Auto retry + account switching for Antigravity `429 Resource Exhausted` (streaming and non-streaming)
-- **Observability**: JSONL dumps for request/response/tools/upstream (with size limit + rotation)

+
+## 📦 Manual Deployment
+
+### Step 1: Environment Setup
+
+**Ubuntu/Debian users:**
 ```bash
-cp .env.example .env
-cp config/config.example.js config/config.js
+# Install Node.js
+curl -fsSL https://deb.nodesource.com/setup_18.x | sudo -E bash -
+sudo apt-get install -y nodejs
 
-# Edit .env at least:
-# JWT_SECRET=... (random string)
-# ENCRYPTION_KEY=... (32-char random string)
-
-docker-compose up -d
+# Install Redis
+sudo apt update
+sudo apt install redis-server
+sudo systemctl start redis-server
 ```
 
-### Node (no Docker)
+**CentOS/RHEL users:**
+```bash
+# Install Node.js
+curl -fsSL https://rpm.nodesource.com/setup_18.x | sudo bash -
+sudo yum install -y nodejs
+
+# Install Redis
+sudo yum install redis
+sudo systemctl start redis
+```
+
+### Step 2: Download and Configure
 
 ```bash
+# Download project
+git clone https://github.com/Wei-Shaw/claude-relay-service.git
+cd claude-relay-service
+
+# Install dependencies
 npm install
-cp .env.example .env
+
+# Copy configuration files (Important!)
 cp config/config.example.js config/config.js
-npm run setup
-npm run service:start:daemon
+cp .env.example .env
 ```
 
-### Admin UI
+### Step 3: Configuration File Setup
 
-- URL: `http://<host>:3000/web`
-- Initial credentials: generated by `npm run setup` and saved to `data/init.json` (Docker users can also inspect container logs).
+**Edit `.env` file:**
+```bash
+# Generate these two keys randomly, but remember them
+JWT_SECRET=your-super-secret-key
+ENCRYPTION_KEY=32-character-encryption-key-write-randomly
+
+# Redis configuration
+REDIS_HOST=localhost
+REDIS_PORT=6379
+REDIS_PASSWORD=
+```
+
+**Edit `config/config.js` file:**
+```javascript
+module.exports = {
+  server: {
+    port: 3000,          // Service port, can be changed
+    host: '0.0.0.0'     // Don't change
+  },
+  redis: {
+    host: '127.0.0.1',  // Redis address
+    port: 6379          // Redis port
+  },
+  // Keep other configurations as default
+}
+```
+
+### Step 4: Start Service
+
+```bash
+# Initialize
+npm run setup # Will randomly generate admin account password info, stored in data/init.json
+
+# Start service
+npm run service:start:daemon   # Run in background (recommended)
+
+# Check status
+npm run service:status
+```

-## Using with Claude Code (CLI)
+## 🎮 Getting Started
 
-### Antigravity pool (recommended)
+### 1. Open Management Interface
+
+Browser visit: `http://your-server-IP:3000/web`
+
+Default admin account: Look in data/init.json
+
+### 2. Add Claude Account
+
+This step is quite important, requires OAuth authorization:
+
+1. Click "Claude Accounts" tab
+2. If you're worried about multiple accounts sharing 1 IP getting banned, you can optionally set a static proxy IP
+3. Click "Add Account"
+4. Click "Generate Authorization Link", will open a new page
+5. Complete Claude login and authorization in the new page
+6. Copy the returned Authorization Code
+7. Paste to page to complete addition
+
+**Note**: If you're in China, this step may require VPN.
+
+### 3. Create API Key
+
+Assign a key to each user:
+
+1. Click "API Keys" tab
+2. Click "Create New Key"
+3. Give the key a name, like "Zhang San's Key"
+4. Set usage limits (optional)
+5. Save, note down the generated key
+
+### 4. Start Using Claude Code and Gemini CLI
+
+Now you can replace the official API with your own service:
+
+**Claude Code Set Environment Variables:**
+
+Default uses standard Claude account pool:
+
+```bash
+export ANTHROPIC_BASE_URL="http://127.0.0.1:3000/api/" # Fill in your server's IP address or domain
+export ANTHROPIC_AUTH_TOKEN="API key created in the backend"
+```
+
+**VSCode Claude Plugin Configuration:**
+
+If using VSCode Claude plugin, configure in `~/.claude/config.json`:
+
+```json
+{
+    "primaryApiKey": "crs"
+}
+```
+
+If the file doesn't exist, create it manually. Windows users path is `C:\Users\YourUsername\.claude\config.json`.
+
+**Gemini CLI Set Environment Variables:**
+
+**Method 1 (Recommended): Via Gemini Assist API**
+
+Each account enjoys 1000 requests per day, 60 requests per minute free quota.
+
+```bash
+CODE_ASSIST_ENDPOINT="http://127.0.0.1:3000/gemini"  # Fill in your server's IP address or domain
+GOOGLE_CLOUD_ACCESS_TOKEN="API key created in the backend"
+GOOGLE_GENAI_USE_GCA="true"
+GEMINI_MODEL="gemini-2.5-pro"
+```
+
+> **Note**: gemini-cli console will show `Failed to fetch user info: 401 Unauthorized`, but this doesn't affect usage.
+
+**Method 2: Via Gemini API**
+
+Very limited free quota, easily triggers 429 errors.
+
+```bash
+GOOGLE_GEMINI_BASE_URL="http://127.0.0.1:3000/gemini"  # Fill in your server's IP address or domain
+GEMINI_API_KEY="API key created in the backend"
+GEMINI_MODEL="gemini-2.5-pro"
+```
+
+**Use Claude Code:**
 
 ```bash
-export ANTHROPIC_BASE_URL="http://<host>:3000/antigravity/api/"
-export ANTHROPIC_AUTH_TOKEN="cr_xxxxxxxxxxxx"
-export ANTHROPIC_MODEL="claude-opus-4-5"
 claude
 ```
 
-### Gemini pool
+**Use Gemini CLI:**
 
 ```bash
-export ANTHROPIC_BASE_URL="http://<host>:3000/gemini-cli/api/"
-export ANTHROPIC_AUTH_TOKEN="cr_xxxxxxxxxxxx"
-export ANTHROPIC_MODEL="gemini-2.5-pro"
-claude
-```
-
-### Standard Claude pool
-
-```bash
-export ANTHROPIC_BASE_URL="http://<host>:3000/api/"
-export ANTHROPIC_AUTH_TOKEN="cr_xxxxxxxxxxxx"
-claude
+gemini
 ```

-## Antigravity Quota & Models
+## 🔧 Daily Maintenance
 
-- Quota display: in Admin UI -> Accounts -> `gemini-antigravity` -> click **Test/Refresh**.
-- Dynamic models list:
-  - Anthropic/Claude Code routing: `GET /antigravity/api/v1/models` (proxies Antigravity `fetchAvailableModels`)
-  - OpenAI-compatible routing: `GET /openai/gemini/models` (or `GET /openai/gemini/v1/models`)
+### Service Management
+
+```bash
+# Check service status
+npm run service:status
+
+# View logs
+npm run service:logs
+
+# Restart service
+npm run service:restart:daemon
+
+# Stop service
+npm run service:stop
+```
+
+### Monitor Usage
+
+- **Web Interface**: `http://your-domain:3000/web` - View usage statistics
+- **Health Check**: `http://your-domain:3000/health` - Confirm service is normal
+- **Log Files**: Various log files in `logs/` directory
+
+### Upgrade Guide
+
+When a new version is released, follow these steps to upgrade the service:
+
+```bash
+# 1. Navigate to project directory
+cd claude-relay-service
+
+# 2. Pull latest code
+git pull origin main
+
+# If you encounter package-lock.json conflicts, use the remote version
+git checkout --theirs package-lock.json
+git add package-lock.json
+
+# 3. Install new dependencies (if any)
+npm install
+
+# 4. Restart service
+npm run service:restart:daemon
+
+# 5. Check service status
+npm run service:status
+```
+
+**Important Notes:**
+- Before upgrading, it's recommended to backup important configuration files (.env, config/config.js)
+- Check the changelog to understand if there are any breaking changes
+- Database structure changes will be migrated automatically if needed
+
+### Common Issue Resolution
+
+**Can't connect to Redis?**
+```bash
+# Check if Redis is running
+redis-cli ping
+
+# Should return PONG
+```
+
+**OAuth authorization failed?**
+- Check if proxy settings are correct
+- Ensure normal access to claude.ai
+- Clear browser cache and retry
+
+**API request failed?**
+- Check if API Key is correct
+- View log files for error information
+- Confirm Claude account status is normal

 ---
 
-## License
+## Caddy Solution
 
-This project is licensed under the [MIT License](LICENSE).
+Caddy is a web server that automatically manages HTTPS certificates, with simple configuration and excellent performance, ideal for deployments without Docker environments.
 
+**1. Install Caddy**
+
+```bash
+# Ubuntu/Debian
+sudo apt install -y debian-keyring debian-archive-keyring apt-transport-https
+curl -1sLf 'https://dl.cloudsmith.io/public/caddy/stable/gpg.key' | sudo gpg --dearmor -o /usr/share/keyrings/caddy-stable-archive-keyring.gpg
+curl -1sLf 'https://dl.cloudsmith.io/public/caddy/stable/debian.deb.txt' | sudo tee /etc/apt/sources.list.d/caddy-stable.list
+sudo apt update
+sudo apt install caddy
+
+# CentOS/RHEL/Fedora
+sudo yum install yum-plugin-copr
+sudo yum copr enable @caddy/caddy
+sudo yum install caddy
+```
+
+**2. Caddy Configuration**
+
+Edit `/etc/caddy/Caddyfile`:
+
+```caddy
+your-domain.com {
+    # Reverse proxy to local service
+    reverse_proxy 127.0.0.1:3000 {
+        # Support streaming responses or SSE
+        flush_interval -1
+
+        # Pass real IP
+        header_up X-Real-IP {remote_host}
+        header_up X-Forwarded-For {remote_host}
+        header_up X-Forwarded-Proto {scheme}
+
+        # Long read/write timeout configuration
+        transport http {
+            read_timeout 300s
+            write_timeout 300s
+            dial_timeout 30s
+        }
+    }
+
+    # Security headers
+    header {
+        Strict-Transport-Security "max-age=31536000; includeSubDomains"
+        X-Frame-Options "DENY"
+        X-Content-Type-Options "nosniff"
+        -Server
+    }
+}
+```
+
+**3. Start Caddy**
+
+```bash
+sudo caddy validate --config /etc/caddy/Caddyfile
+sudo systemctl start caddy
+sudo systemctl enable caddy
+sudo systemctl status caddy
+```
+
+**4. Service Configuration**
+
+Since Caddy automatically manages HTTPS, you can restrict the service to listen locally only:
+
+```javascript
+// config/config.js
+module.exports = {
+  server: {
+    port: 3000,
+    host: '127.0.0.1' // Listen locally only
+  }
+}
+```
+
+**Caddy Features**
+
+* 🔒 Automatic HTTPS with zero-configuration certificate management
+* 🛡️ Secure default configuration with modern TLS suites
+* ⚡ HTTP/2 and streaming support
+* 🔧 Concise configuration files, easy to maintain
+
+---
+
+## Nginx Proxy Manager (NPM) Solution
+
+Nginx Proxy Manager manages reverse proxies and HTTPS certificates through a graphical interface, deployed as a Docker container.
+
+**1. Create a New Proxy Host in NPM**
+
+Configure the Details as follows:
+
+| Item                  | Setting                  |
+| --------------------- | ------------------------ |
+| Domain Names          | relay.example.com        |
+| Scheme                | http                     |
+| Forward Hostname / IP | 192.168.0.1 (docker host IP) |
+| Forward Port          | 3000                     |
+| Block Common Exploits | ☑️                       |
+| Websockets Support    | ❌ **Disable**            |
+| Cache Assets          | ❌ **Disable**            |
+| Access List           | Publicly Accessible      |
+
+> Note:
+> - Ensure Claude Relay Service **listens on `0.0.0.0`, container IP, or host IP** to allow NPM internal network connections.
+> - **Websockets Support and Cache Assets must be disabled**, otherwise SSE / streaming responses will fail.
+
+**2. Custom locations**
+
+No content needed, keep it empty.
+
+**3. SSL Settings**
+
+* **SSL Certificate**: Request a new SSL Certificate (Let's Encrypt) or existing certificate
+* ☑️ **Force SSL**
+* ☑️ **HTTP/2 Support**
+* ☑️ **HSTS Enabled**
+* ☑️ **HSTS Subdomains**
+
+**4. Advanced Configuration**
+
+Add the following to Custom Nginx Configuration:
+
+```nginx
+# Pass real user IP
+proxy_set_header X-Real-IP $remote_addr;
+proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
+proxy_set_header X-Forwarded-Proto $scheme;
+
+# Support WebSocket / SSE streaming
+proxy_http_version 1.1;
+proxy_set_header Upgrade $http_upgrade;
+proxy_set_header Connection "upgrade";
+proxy_buffering off;
+
+# Long connection / timeout settings (for AI chat streaming)
+proxy_read_timeout 300s;
+proxy_send_timeout 300s;
+proxy_connect_timeout 30s;
+
+# ---- Security Settings ----
+# Strict HTTPS policy (HSTS)
+add_header Strict-Transport-Security "max-age=31536000; includeSubDomains" always;
+
+# Block clickjacking and content sniffing
+add_header X-Frame-Options "DENY" always;
+add_header X-Content-Type-Options "nosniff" always;
+
+# Referrer / Permissions restriction policies
+add_header Referrer-Policy "no-referrer-when-downgrade" always;
+add_header Permissions-Policy "camera=(), microphone=(), geolocation=()" always;
+
+# Hide server information (equivalent to Caddy's `-Server`)
+proxy_hide_header Server;
+
+# ---- Performance Tuning ----
+# Disable proxy caching for real-time responses (SSE / Streaming)
+proxy_cache_bypass $http_upgrade;
+proxy_no_cache $http_upgrade;
+proxy_request_buffering off;
+```
+
+**5. Launch and Verify**
+
+* After saving, wait for NPM to automatically request Let's Encrypt certificate (if applicable).
+* Check Proxy Host status in Dashboard to ensure it shows "Online".
+* Visit `https://relay.example.com`, if the green lock icon appears, HTTPS is working properly.
+
+**NPM Features**
+
+* 🔒 Automatic certificate application and renewal
+* 🔧 Graphical interface for easy multi-service management
+* ⚡ Native HTTP/2 / HTTPS support
+* 🚀 Ideal for Docker container deployments
+
+---
+
+Both solutions are suitable for production deployment. If you use a Docker environment, **Nginx Proxy Manager is more convenient**; if you want to keep software lightweight and automated, **Caddy is a better choice**.
+
+---
+
+## 💡 Usage Recommendations
+
+### Account Management
+- **Regular Checks**: Check account status weekly, handle exceptions promptly

+
+### Security Recommendations
+- **Use HTTPS**: Strongly recommend using Caddy reverse proxy (automatic HTTPS) to ensure secure data transmission
+- **Regular Backups**: Back up important configurations and data
+- **Monitor Logs**: Regularly check exception logs
+- **Update Keys**: Regularly change JWT and encryption keys
+- **Firewall Settings**: Only open necessary ports (80, 443), hide direct service ports
+
+---
+
+## 🆘 What to Do When You Encounter Problems?
+
+### Self-troubleshooting
+1. **Check Logs**: Log files in `logs/` directory
+2. **Check Configuration**: Confirm configuration files are set correctly
+3. **Test Connectivity**: Use curl to test if API is normal
+4. **Restart Service**: Sometimes restarting fixes it
+
