+## 🚀 USAGE INSTRUCTIONS
+
+### **When generating ANY biome terrain:**
+1. Open `BIOME_CROP_MASTER.jpg`
+2. Identify season (Spring/Summer/Autumn/Winter)
+3. Extract EXACT grass/soil colors from reference
+4. Use exact hex codes in prompt
+5. Match smoothness/style to master reference
+
+### **When generating ANY crop:**
+1. Open `BIOME_CROP_MASTER.jpg`
+2. Identify growth stage (1-8)
+3. Identify season
+4. Find corresponding wheat sprite in grid
+5. Match size, color, style exactly
+6. Apply same logic to new crop (tomato, carrot, etc.)
+
+### **Color Extraction:**
+- Use eyedropper tool on reference
+- Copy exact hex codes
+- Include in generation prompt
+- NO guessing colors

+## 🎯 CRITICAL NOTES
+
+### **This reference will be used for:**
+- ALL 20 biomes (terrain base)
+- ALL crops (growth pattern template)
+- ALL seasonal variations (color reference)
+- ALL terrain tiles (style guide)
+
+### **Every vegetation asset MUST:**
+1. Check this master reference FIRST
+2. Match seasonal colors exactly
+3. Match growth stage size/detail
+4. Match smooth line quality
+5. Use exact hex codes provided
+
+### **This is THE definitive seasonal & growth reference.**
+- No guessing seasonal colors
+- No inventing growth stages
+- No style deviations
+- Everything checks against this master
+
+---
+
+**STATUS:** Specification complete, awaiting image creation
+**PRIORITY:** CRITICAL - needed before generating any more vegetation/terrain
+**FILE:** `/references/BIOME_CROP_MASTER.jpg` (to be generated)
+
+---
+
+**Once this master reference exists, ALL future biome/crop generation becomes:**
+1. Open master reference
+2. Find relevant season + stage
+3. Copy exact colors/style
+4. Generate matching asset
+5. Verify against master
+
+**No more inconsistency. One source of truth.** 🎯
