## Building using the Dockerfile
It's possible to use a docker image for building. This way you don't need anything installed on your host system.
```
# Build docker image (only needed once)
docker build . -t rpxloadingmodule-builder
# make
docker run -it --rm -v ${PWD}:/project rpxloadingmodule-builder make
# make clean
docker run -it --rm -v ${PWD}:/project rpxloadingmodule-builder make clean
```
