+```
+
+## Current Status
+
+⚠️ **IMPORTANT**: These GGUF files contain all loop attention tensors and metadata, but **runtime support is pending** in llama.cpp.
+
+**What Works**:
+- ✅ GGUF files load correctly
+- ✅ All 883 tensors preserved (721 standard + 160 loop gates + 2 embeddings)
+- ✅ Loop parameters stored in metadata (loop_num=2, loop_window_size=64)
+- ✅ Quantization tested and verified
+
+**What's Pending**:
+- ⏳ Loop attention runtime implementation in llama.cpp
+- ⏳ Inference will fail until runtime support added
+
+## Technical Details
+
+### Loop Architecture
+
+The IQuest Loop Coder uses a **recurrent transformer design** with:
+- **loop_num**: 2 iterations of attention per layer
+- **loop_window_size**: 64 token attention window
+- **Gate Projections**: 160 additional tensors for gating mechanism
+  - `blk.-79.loop_gate.weight`: [128, 40] per layer
+  - `blk.-79.loop_gate.bias`: [40] per layer
+
+### Conversion Process
+
+Converted using custom `IQuestLoopCoderModel` class:
+- Inherits from LlamaModel (compatible base architecture)
+- Maps gate_projections to GGUF tensor names
+- Preserves loop parameters in metadata
+- Tested with all quantization levels
+
+Conversion time: **2-7 minutes** per quantization on NVIDIA GB10
+
+## Usage (When Runtime Support Available)
+
+### With Ollama
+
+```bash
+# Create Modelfile
+cat > Modelfile <<EOF
+FROM IQuest-Coder-V1-40B-Loop-Instruct-q4_k_m.gguf
+PARAMETER temperature 0.7
+PARAMETER top_p 0.9
+EOF
+
+# Create model
+ollama create iquest-loop:q4 -f Modelfile
+
+# Run
+ollama run iquest-loop:q4 "Write a Python function for fibonacci"
+```
+
+### With llama.cpp
+
+```bash
+./llama-cli \
+    --model IQuest-Coder-V1-40B-Loop-Instruct-q4_k_m.gguf \
+    --prompt "def fibonacci(n):" \
+    --n-predict 100
+```
+
+**Note**: Will fail until loop attention runtime is implemented.
+
+## Implementation Status
+
+### Converter ✅ (Complete)
+
+The converter successfully creates GGUF files with all loop-specific components:
+- Custom tensor mapping for gate projections
+- Loop parameter metadata storage
+- Tested with 40B parameter model
+- All quantization levels verified
+
+### Runtime ⏳ (In Progress)
+
+Runtime implementation requires:
+1. C++ implementation of loop attention mechanism
+2. CUDA kernels for GPU acceleration
+3. Integration into llama.cpp forward pass
+4. Testing against PyTorch reference
+
+See `RUNTIME_IMPLEMENTATION_GUIDE.md` for detailed implementation requirements.
