 # RVC Text-to-Speech
 
-This is a text-to-speech using [RVC](https://github.com/RVC-Project/Retrieval-based-Voice-Conversion-WebUI) and [edge-tts](https://github.com/rany2/edge-tts).

+This is a text-to-speech using [RVC](https://github.com/RVC-Project/Retrieval-based-Voice-Conversion-WebUI) and [edge-tts](https://github.com/rany2/edge-tts).
+
+## Install
+
+Requirements: Checked for Python 3.10 on Windows 11.
+
+```bash
+git clone https://github.com/litagin02/rvc-tts.git
+cd rvc-tts
+
+# Download models
+curl -L -O https://huggingface.co/lj1995/VoiceConversionWebUI/resolve/main/hubert_base.pt
+curl -L -O https://huggingface.co/lj1995/VoiceConversionWebUI/resolve/main/rmvpe.pt
+
+# Make virtual environment
+python -m venv venv
+## Windows
+venv\Scripts\activate
+
+# Install PyTorch
+# See https://pytorch.org/get-started/locally/ for more details
+
+## For Windows with NVIDIA GPU
+pip install torch torchvision torchaudio --index-url https://download.pytorch.org/whl/cu118
+## For Windows with CPU
+pip install torch torchvision torchaudio
+
+# Install requirements
+
+pip install -r requirements.txt
+```
+
+## Locate RVC models
+
+Locate your RVC models in `weights/` directory as follows:
+
+```bash
+weights/
+├── model1/
+│   ├── model1.pth
+│   └── index_file.index
+└── model2/
+    ├── model2.pth
+    └── index_file.index
+...
+```
+
+Each model directory should contain exactly one `.pth` file and at most one `.index` file.
+
+## Launch
+
+```bash
+python app.py
+```
