-AutoGGUF provides a graphical user interface for quantizing GGUF models using the llama.cpp library. It allows users to download different versions of llama.cpp, manage multiple backends, and perform quantization tasks with various options.
+The most comprehensive GUI tool for GGUF model quantization. Stop wrestling with command lines - quantize, merge, and optimize your models with just a few clicks.

 ## Features

- Download and manage llama.cpp backends
- Select and quantize GGUF models
- Configure quantization parameters
- Monitor system resources during quantization
- Parallel quantization + imatrix generation
- LoRA conversion and merging
- Preset saving and loading
- AutoFP8 quantization
- GGUF splitting
+- 📩 Update and manage llama.cpp backends
+- 🗃️ Download and quantize GGUF/safetensors models
+- 📐 Configure quantization parameters
+- 💻 Monitor system resources in real time during quantization
+- ⏳ Parallel quantization + imatrix generation
+- 🎉 LoRA conversion and merging
+- 📁 Preset saving and loading
+- 8️⃣ AutoFP8 quantization
+- 🪓 GGUF splitting and merging
+- 🌐 HTTP API for automation and monitoring

-## Usage
+## Why AutoGGUF?
+- Fast: Saves time on manual configuration

- Some inconsistent logging
+- Some inconsistent logging and signal handling
+- Missing or duplicated translations (priority)
+- Buggy/incomplete API interfaces
+- Code review and formatting (priority)

 ## Planned Features

- Time estimation for quantization
- Quantization file size estimate
- Perplexity testing
- HuggingFace upload/download (coming in the next release)
- bitsandbytes (coming soon)
+- [ ] Time estimation for quantization
+- [ ] Quantization file size estimate
+- [ ] Perplexity testing
+- [ ] bitsandbytes support

-## Troubleshooting
+#### Project Status
+
+AutoGGUF has now entered maintenance mode. It's considered stable and feature-complete for most use cases, so I'm not actively developing new features, but I’ll continue to publish occasional builds, update dependencies regularly, and fix critical bugs as needed. If you encounter issues or have suggestions, feel free to open an issue.
+
+## Support

 - SSL module cannot be found error: Install OpenSSL or run from source using `python src/main.py` with the `run.bat` script (`pip install requests`)
+- Check out the [Wiki](https://github.com/leafspark/AutoGGUF/wiki) for advanced usage and configuration
