+Take a video and replace the face in it with a face of your choice. You only need one image of the desired face. No dataset, no training.
+
+That's it, that's the software.
+
+![demo-gif](demo.gif)
+
+## Installation
+> Do not create any issues regarding installation problems. I am only responsible for issues in this program, use google for help.
+
+1. install `python`, `pip` and `git`
+2. install `ffmpeg`
+3. run the following commands in terminal:
+```
+git clone https://github.com/s0md3v/roop
+cd roop
+pip3 install -r requirements.txt
+```
+
+### Do you have a decent GPU?
+If you have a good enough GPU, you can use it to speed up the face-swapping process by running `run.py` with `--gpu` flag.
+If you plan on doing, you will need to install the appropriate `onnxruntime-*` package as follows:
+
+#### NVIDIA
+```
+pip3 install onnxruntime-gpu
+```
+#### AMD
+```
+git clone https://github.com/microsoft/onnxruntime
+cd onnxruntime
+./build.sh --config Release --build_wheel --update --build --parallel --cmake_extra_defines CMAKE_PREFIX_PATH=/opt/rocm/lib/cmake ONNXRUNTIME_VERSION=$ONNXRUNTIME_VERSION onnxruntime_BUILD_UNIT_TESTS=off --use_rocm --rocm_home=/opt/rocm
+pip install build/Linux/Release/dist/*.whl
+```
+
+## Usage
+> Note: When you run this program for the first time, it will download some models ~300MB in size.
+
+Executing `python run.py` command will launch this window:
+
+Choose a face (image with desired face) and the target image/video (image/video in which you want to replace the face) and click on `Start`. The output will be saved in `output.mp4` file.
+
+Don't touch the FPS checkbox unless you know what you are doing.
+
+Additional command line arguments are given below:
+```
+-h, --help            show this help message and exit
+-f SOURCE_IMG, --face SOURCE_IMG
+                        use this face
+-t TARGET_PATH, --target TARGET_PATH
+                        replace this face
+--keep-fps            keep original fps
+--gpu                 use gpu
+--keep-frames         don't delete frames directory
+```
+
+Looking for a CLI mode? Using the -f/--face argument will make the program in cli mode.
+
+## Future plans
+- [ ] Replace a selective face throughout the video
+- [ ] Support for replacing multiple faces
+
+## Credits
+- [ffmpeg](https://ffmpeg.org/): for making video related operations easy
+- [deepinsight](https://github.com/deepinsight): for their [insightface](https://github.com/deepinsight/insightface) project which provided a well-made library and models.
+- and all developers behind libraries used in this project.
