## Launching Steam in Docker
You may want to re-run this command later on in order to keep the image updated.
The simplest way to launch Steam is by running:
```
```sh
docker build -t andrey01/steam .
git clone https://github.com/arno01/steam.git
cd steam
docker-compose run steam
```
```
If Steam does not start, you may need to allow your user making local
