### 🔧 **If You See Warnings**
**Don't worry!** The package is designed to work even with warnings:
#### ⚠️ "API key warning is normal"
- **What it means**: PERPLEXITY_API_KEY not set
- **Impact**: Analytics and models work, API calls need key
- **Fix**: `export PERPLEXITY_API_KEY="your-key"`
#### ⚠️ "Cache system has issues"
- **What it means**: Cache initialization failed
- **Impact**: Still works, just no caching
- **Fix**: Usually resolves on restart
#### ⚠️ "Directory write permissions limited"
- **What it means**: Can't write log files
- **Impact**: Logging goes to console only
- **Fix**: Run from writable directory
