The recipe for any data set is roughly the same as the tutorial[1][2]:

1. load you road network into postGIS as a table
2. create a network topology using assign_vertex_id() or if you have 
zlevels then you might need to find a copy or modify assign_vertex_id() 
to handle zlevels.
3. update your cost and reverse cost columns based on one-way streets
4. you should be good to go to test the basic system
5. if you want to use turn restrictions read the docs and ask on the 
list. This is a lot harder at the moment to use.
