+### Cache Management
+
+soundcoe automatically manages audio file caching for optimal performance:
+
+```cpp
+// Standard cache limits
+soundcoe::initialize("./audio", 32, 64);       // 64MB cache limit
+soundcoe::initialize("./audio", 32, 256);      // 256MB cache limit
+
+// Development/Testing: measure actual memory usage
+soundcoe::initialize("./audio", 32, soundcoe::UNLIMITED_CACHE);
+```
+
+**Development Tip**: Use `soundcoe::UNLIMITED_CACHE` during testing to measure your game's peak audio memory usage, then set an appropriate limit for your target platforms.

 ### Source Pool Optimization
 
 ```cpp
 // Configure source pool based on your game - choose how many sources that you would like! remember it is the maximum concurrent amount.
-soundcoe::initialize("./audio", 16);         // 16 sources for games with less concurrent audio

 ### Caching Strategy
 - **LRU Eviction**: Least recently used buffers removed first
 - **Size Limits**: Configurable maximum cache size in MB
+- **Unlimited Cache**: Use `soundcoe::UNLIMITED_CACHE` for development/profiling to measure peak memory usage
 - **Usage Tracking**: Statistical data for optimization decisions
