 ## Installation 🛠️
 
+### 🐳 Docker
+
+If you're able to use docker, you don't actually need to _install_ anything - there are [images published on Docker Hub](https://hub.docker.com/r/beveradb/audio-separator/tags) for GPU (CUDA) and CPU inferencing, for both `amd64` and `arm64` platforms.
+
+You probably want to volume-mount a folder containing whatever file you want to separate, which can then also be used as the output folder.
+
+For instance, if your current directory has the file `input.wav`, you could execute `audio-separator` as shown below (see [usage](#usage-) section for more details):
+
+```
+docker run -it -v `pwd`:/workdir beveradb/audio-separator input.wav
+```
+
+If you're using a machine with a GPU, you'll want to use the GPU specific image and pass in the GPU device to the container, like this:
+
+```
+docker run -it --gpus all -v `pwd`:/workdir beveradb/audio-separator:gpu input.wav
+```
+
+If the GPU isn't being detected, make sure your docker runtime environment is passing through the GPU correctly - there are [various guides](https://www.celantur.com/blog/run-cuda-in-docker-on-linux/) online to help with that.

+You can use Audio Separator via the command line, for example:
 
 ```
-docker run -it --gpus all -v `pwd`:/workdir beveradb/audio-separator:gpu input.wav

+This command will download the specified model file, process the `audio.wav` input audio and generate two new files in the current directory, one containing vocals and one containing instrumental.
 
+**Note:** You do not need to download any files yourself - audio-separator does that automatically for you!
 
-## Usage 🚀
+To see a list of supported models, run `audio-separator --list_models`
 
-### Command Line Interface (CLI)
+Any file listed in the list models output can be specified (with file extension) with the model_filename parameter (e.g. `--model_filename UVR_MDXNET_KARA_2.onnx`) and it will be automatically downloaded to the `--model_file_dir` (default: `/tmp/audio-separator-models/`) folder on first usage.
