Answer: **No, you don't need the `info` and `docs` directories to view the documentation!**

Here's what I found:

### 📚 **Core Documentation Structure**

The documentation system has **three levels**:

1. **📁 `book/` directory** - **Required** - Main documentation source
   - Contains the complete mdBook documentation structure
   - Has 80 pages of comprehensive guides
   - Includes all essential content for using Rustelo

2. **📁 `docs/` directory** - **Optional** - Supplementary documentation
   - Contains additional technical documentation
   - Used for enhanced content when building with `--sync`

3. **📁 `info/` directory** - **Optional** - Development notes
   - Contains development notes and implementation details
   - Used for enhanced content when building with `--sync`

### ✅ **What Works Without `info` and `docs`**

**Basic documentation build:**
```bash
just docs-build
```
- ✅ Builds successfully (80 pages, 3.2M)
- ✅ Complete user documentation
- ✅ All essential guides and tutorials
- ✅ Feature documentation
- ✅ API reference
- ✅ Getting started guides

**With sync (uses `info` and `docs`):**
```bash
just docs-build-sync
```
- ✅ Builds successfully (80 pages, 3.7M)
- ✅ Includes additional technical details
- ✅ Enhanced feature documentation
- ✅ Development implementation notes

### 🎯 **Recommendation**

**For normal use**: Just keep the `book/` directory - it contains everything users need to work with Rustelo.

**For development**: Keep all three directories if you want the most comprehensive documentation with all implementation details.

The `book/` directory alone provides:
- Complete getting started guide
- All feature documentation
- Configuration guides
- Deployment instructions
- API reference
- Security guides
- Troubleshooting
- And much more!

So you can safely **remove or ignore the `info` and `docs` directories** if you want a lighter template, and the documentation will still work perfectly! 🚀
