+
+## Model Details
+
+- **Base Model:** {BASE_MODEL}
+- **Fine-tuned Model:** {ADAPTER_MODEL}
+- **Training:** SFT on code datasets (Codeforces, Golang, Vue/Nuxt, React)
+- **Quantization:** Q8_0 (8-bit, high quality)
+
+## Usage
+
+### With Ollama
+
+```bash
+huggingface-cli download {OUTPUT_REPO} {model_name}-q8_0.gguf
+echo "FROM ./{model_name}-q8_0.gguf" > Modelfile
+ollama create qwen3-multicode -f Modelfile
+ollama run qwen3-multicode
+```
+
+### With llama.cpp
+
+```bash
+huggingface-cli download {OUTPUT_REPO} {model_name}-q8_0.gguf
+./llama-cli -m {model_name}-q8_0.gguf -p "Write a React component"
+```
+
+### With LM Studio
+
+Download the `.gguf` file and import into LM Studio.
