+# 🔧 Hugging Face Spaces Configuration
+
+## YAML Front Matter Configuration
+
+File `README.md` harus dimulai dengan YAML front matter configuration:
+
+```yaml
+---
+title: FunCaptcha Solver API
+emoji: 🧩
+colorFrom: blue
+colorTo: purple
+sdk: docker
+pinned: false
+suggested_hardware: cpu-basic
+app_file: app.py
+---
+```
+
+## 📋 Configuration Options
+
+### **Required Fields**
+
+| Field | Value | Description |
+|---|---|---|
+| `sdk` | `docker` | **CRITICAL**: Must be "docker" for Docker-based spaces |
+| `title` | `FunCaptcha Solver API` | Display name di HF Spaces |
+
+### **Optional Fields**
+
+| Field | Default Value | Description | Options |
+|---|---|---|---|
+| `emoji` | `🧩` | Icon untuk space | Any emoji |
+| `colorFrom` | `blue` | Gradient start color | blue, red, green, yellow, etc. |
+| `colorTo` | `purple` | Gradient end color | purple, pink, orange, etc. |
+| `pinned` | `false` | Pin space di profile | `true` / `false` |
+| `app_file` | `app.py` | Main application file | Any Python file |
+| `suggested_hardware` | `cpu-basic` | Hardware suggestion | See below |
+
+### **Hardware Options**
+
+| Hardware | Description | Use Case |
+|---|---|---|
+| `cpu-basic` | **2 vCPU, 16GB RAM** | ✅ **Recommended untuk FunCaptcha** |
+| `cpu-upgrade` | 8 vCPU, 32GB RAM | Heavy ML workloads |
+| `t4-small` | GPU T4, 15GB VRAM | GPU-accelerated inference |
+| `t4-medium` | GPU T4, 60GB RAM | Large GPU models |
+
+> 💡 **Tip**: `cpu-basic` sudah cukup untuk FunCaptcha solver dengan optimasi yang sudah diterapkan.
+
+## 🚨 Common Configuration Errors
+
+### **Error: "Missing configuration in README"**
+
+**Cause**: README.md tidak dimulai dengan YAML front matter
+
+**Solution**: 
+```yaml
+# ❌ WRONG - Missing YAML front matter
+# FunCaptcha Solver API
+
+# ✅ CORRECT - With YAML front matter  
+---
+title: FunCaptcha Solver API
+emoji: 🧩
+sdk: docker
+---
+
+# FunCaptcha Solver API
+```
+
+### **Error: "Invalid SDK configuration"**
+
+**Cause**: `sdk` field salah atau missing
+
+**Solution**:
+```yaml
+# ❌ WRONG
+sdk: python
+# or missing sdk field
+
+# ✅ CORRECT
+sdk: docker
+```
+
+### **Error: "Space fails to start"**
+
+**Possible causes & solutions**:
+
+1. **Dockerfile issues**
+   - Check Dockerfile syntax
+   - Verify all dependencies installed
+   - Check port 7860 exposed
+
+2. **Missing model files**
+   - Upload `best.onnx` dan `data.yaml`
+   - Check file paths in app.py
+
+3. **Missing API key**
+   - Set `FUNCAPTCHA_API_KEY` di space secrets
+   - Verify secret name exactly matches
+
+## 🛠️ Customization Options
+
+### **Custom Title & Branding**
+
+```yaml
+---
+title: Your Custom FunCaptcha API
+emoji: 🤖
+colorFrom: green
+colorTo: blue
+---
+```
+
+### **Private Space**
+
+Set space visibility to **Private** during creation (tidak bisa diubah via YAML).
+
+### **Custom App File**
+
+Jika rename `app.py`:
+
+```yaml
+---
+sdk: docker
+app_file: main.py  # Your custom filename
+---
+```
+
+### **Hardware Upgrade**
+
+Untuk performa lebih tinggi:
+
+```yaml
+---
+sdk: docker
+suggested_hardware: cpu-upgrade  # More powerful CPU
+---
+```
+
+## 🔍 Validation Checklist
+
+Sebelum deploy, pastikan:
+
+- [ ] README.md dimulai dengan `---`
+- [ ] `sdk: docker` field present
+- [ ] `title` field specified
+- [ ] YAML format valid (no tabs, proper indentation)
+- [ ] File ends dengan `---` dan newline
+- [ ] No syntax errors dalam YAML
+
+## 🧪 Testing Configuration
+
+```bash
+# Test YAML syntax locally
+python -c "import yaml; yaml.safe_load(open('README.md').read().split('---')[1])"
+
+# Check for required fields
+grep -E "^(sdk|title):" README.md
+```
+
+## 📝 Template untuk Custom Spaces
+
+```yaml
+---
+title: "Your App Name"
+emoji: 🚀
+colorFrom: blue
+colorTo: purple  
+sdk: docker
+pinned: false
+suggested_hardware: cpu-basic
+app_file: app.py
+license: mit
+short_description: "Brief description of your space"
+---
+
+# Your App Name
+
+Your app description here...
+```
+
+---
+
+**⚠️ CRITICAL**: Tanpa proper YAML front matter, HF Spaces tidak akan recognize space sebagai Docker-based application dan akan fail untuk start!
+
+**✅ Quick Fix**: Copy exact YAML header dari `README.md` yang sudah disediakan dalam deployment package.
