 This document describes how to manually configure your system for running OpenStreetMap Carto. If you prefer quick, platform independent setup for a development environment, without the need to install and configure tools by hand, follow a Docker installation guide in [DOCKER.md](DOCKER.md).
 
 ## OpenStreetMap data
-You need OpenStreetMap data loaded into a PostGIS database (see below for [dependencies](#dependencies)). These stylesheets expect a database generated with osm2pgsql using the pgsql backend (table names of `planet_osm_point`, etc), the default database name (`gis`), and the [lua transforms](https://osm2pgsql.org/doc/manual.html#lua-tag-transformations) documented in the instructions below.

 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
