+- `make osrm-data`: downloads the OpenStreetMap data for Wisconsin, and preproccesses it for use with OSRM.
+- `make osrm-container`: starts the OSRM containers (backends and frontends) for walking and biking.
+- `make brouter-data`: clones the repositories for brouter and brouter-web and downloads the segment data. It also builds the docker images for brouter and brouter-web.
