Now you can issue your regular buildroot commands, like `make menuconfig` or `make <boardname>_defconfig` followed by `make`.

## Development
### Building the image
Either simply issue `docker build -t <name> .` or alternatively use the included Docker Compose file using `docker-compose build buildroot`.

### Testing
To validate that the image works correctly a simple test that builds a Raspberry Pi3 image using the default external toolchain can be run using the included Docker Compose file `docker-compose run --rm buildroot`.
