 Then, grab some OSM data; It's probably easiest to grab an PBF of OSM data from [Geofabrik](https://download.geofabrik.de/). Once you've done that, import with osm2pgsql:
 
 ```sh
-osm2pgsql -G --hstore --style openstreetmap-carto.style --tag-transform-script openstreetmap-carto.lua -d gis ~/path/to/data.osm.pbf
+osm2pgsql -O flex -S openstreetmap-carto-flex.lua -d gis ~/path/to/data.osm.pbf
 ```
