-Overview
---------
-The repository provides a Leaflet [(1)] based web frontend to the Open Source Routing Machine (Project-OSRM [(2)]).
-The frontend is implemented in Javascript.
-Data is fetched from routing and geocoding servers using JSONP queries.
-The website is XHTML 1.0 Strict compliant.
-A deployed version of the the web frontend can be seen at [(3)].
+# Readme
 
+For instructions on how to compile and run OSRM, please consult the Wiki at
 
-Setup
------
-The frontend should work directly as provided.
-Several settings - including the URL for the routing server and the geocoder server - can be specified in `OSRM.config.js`.
-Different tile servers can be specified in `OSRM.Map.js`.
-Note that the URL shortener used for generating route links only works with URLs pointing to the official Project-OSRM website.
+https://github.com/DennisOSRM/Project-OSRM/wiki
 
+or use our free and daily updated online service at
 
-Branches
---------
-* The `master` branch will always point to the latest released version of the frontend.
-* The `develop` branch should always point to a working version with new features and bugfixes (think of it as a nightly-build).
-* Other branches contain various work in progress.
+http://map.project-osrm.org
 
+## References in publications
 
-Bugtracking
------------
-Please use the OSRM-Project bug tracker [(4)] for submitting any bug reports or feature requests.
+When using the code in a (scientific) publication, please cite
 
-Integration into Project-OSRM repository
-----------------------------------------
-The Project-OSRM repository already contains the frontend repository as a submodule.
-It will always point to the latest deployed version.
-To successfully work a repository that contains submodules, use the following git commands (available in git 1.7.1+):
+```

-* `git clone --recursive`  
-	to clone a repository and the contained submodules
+## Current build status
 
-* `git pull && git submodule update`  
-	to pull the latest version of the repository and update its submodules if required
-
-Note that the frontend can also be checked out independently of the Project-OSRM repository.
