 # SOME
 SOME: Singing-Oriented MIDI Extractor.
 
-Warning SOME is an alpha version
+> WARNING
+> 
+> This project is under beta version now. No backward compatibility is guaranteed.
+
+## Overview
+
+SOME is a MIDI extractor that can convert singing voice to MIDI sequence, with the following advantages:
+
+1. Speed: 9x faster than real-time on an i5 12400 CPU, and 300x on a 3080Ti GPU.
+2. Low resource dependency: SOME can be trained on custom dataset, and can achieve good results with only 3 hours of training data.
+3. Functionality: SOME can produce non-integer MIDI values, which is specially suitable for DiffSinger variance labeling.
+
+## Getting Started
+
+### Installation
+
+SOME requires Python 3.8 or later. We strongly recommend you create a virtual environment via Conda or venv before installing dependencies.
+
+1. Install PyTorch 2.1 or later following the [official instructions](https://pytorch.org/get-started/locally/) according to your OS and hardware.
+
+2. Install other dependencies via the following command:
+
+   ```bash
+   pip install -r requirements.txt
+   ```
+
+3. (Optional) For better pitch extraction results, please download the RMVPE pretrained model from [here](https://github.com/yxlllc/RMVPE/releases) and extract it into `pretrained/` directory.
+
+### Inference via pretrained model
+
+Download pretrained model of SOME from [releases](https://github.com/openvpi/SOME/releases) and extract them somewhere.
+
+To infer with CLI, run the following command:
+
+```bash
+python infer.py --model CKPT_PATH --wav WAV_PATH
+```
+
+This will load model at CKPT_PATH, extract MIDI from audio file at WAV_PATH and save a MIDI file. For more useful options, run
+
+```bash
+python infer.py --help
+```
+
+To infer with Web UI, run the following command:
+
+```bash
+python webui.py --work_dir WORK_DIR
+```
+
+Then you can open the gradio interface through your browser and use the models under WORK_DIR following the instructions on the web page. For more useful options, run
+
+```bash
+python webui.py --help
+```
+
+### Training from scratch
+
+_Training scripts are uploaded but may not be well-organized yet. For the best compatibility, we suggest training your own model after a stable release in the future._
+
