how to import OSM data into mongodb

hey can anyone tell how to import osm data into mongodb step by step

This is the data link http://download.geofabrik.de/europe/germany/baden-wuerttemberg/karlsruhe-regbez.html

Typing “mongoDB” in the text search field of OSM wiki gives a link to http://wiki.openstreetmap.org/wiki/Osmo and http://wiki.openstreetmap.org/wiki/Databases_and_data_access_APIs

Also I have seen you are doing crossposting at help.osm.org … search there for mongoDB.
