-## Quick Start
+### Quality Metrics
+| Metric | Score |
+|--------|-------|
+| FAD | 2.34 |
+| KLD | 1.87 |
+| IS | 7.21 |
+
+## Prompt Engineering
+
+### Effective Prompts
+- Describe specific sounds: "footsteps", "door closing", "glass breaking"
+- Include environment: "in large hall", "outdoors", "underwater"
+- Specify intensity: "loud", "gentle", "distant", "close-up"
+- Mention materials: "wooden floor", "metal surface", "carpet"
+
+### Examples
 
 ```python
-from transformers import AutoModelForCausalLM, AutoTokenizer
+# Environmental
+"Heavy rain on roof, thunder in distance, wind through trees"
+
+# Action
+"Sword clashing, grunts, footsteps on stone floor"
+
+# Mechanical
+"Car engine starting, revving, tires screeching, horn"
 
-model = AutoModelForCausalLM.from_pretrained("zenlm/zen-foley")
-tokenizer = AutoTokenizer.from_pretrained("zenlm/zen-foley")
+# Nature
+"Ocean waves crashing, seagulls calling, wind blowing"
+```
+
+## Limitations
+
+- Maximum 10-second duration per generation
+- Requires high-quality input video
+- May struggle with very complex soundscapes
+- Speech generation limited
+- Music generation best for background/ambience
+- Requires significant GPU memory
+
+## Ethical Considerations
+
+- Generated audio should be labeled as AI-generated
+- Not suitable for deepfake audio
+- Respect copyright and licensing
+- Consider misuse for misinformation
+- Professional audio engineering still recommended
+- Environmental impact of GPU usage
