title: Launch OSRM server on large area
body: <p>in the tutorial it is shown how to start an OSRM server with this example : </p>
  
  <pre><code>wget http://download.geofabrik.de/europe/germany/berlin-latest.osm.pbf
  
  osrm-extract berlin-latest.osm.pbf -p profiles/car.lua
  osrm-contract berlin-latest.osrm
  osrm-routed berlin-latest.osrm
  </code></pre>
  
  <p>I would like to start a server not only on Berlin dataset, but on a full country dataset. For instance all German country roads. Maybe there is something to do with the contract, but i don't really know what king of .osrm i should put as argument to tell it to use a larger dataset that would be the combination of several dataset. </p>
  
  <p>I think the answer should be really obvious when we know it, but it still feel a bit wooly.</p>
  
  <p>Thank you.</p>
