+## Vector Data Source
+
+This is the data source for the vector tile schema of OSM2VectorTiles.
+It contains the *tm2source* project and the required database schema (views, functions).
+
+The vector data sources stands as separate repository to foster collaboration with Wikipedia
+and make it easier to fork the style without forking OSM2VectorTiles as well.
+
+## Requirements
+
+This vector tile schema depends on a database containing several different data sources
+which need to be imported first. You can use your own ETL process or use the Docker containers from
+OSM2VectorTiles.
+
+Your PostGIS database needs the following data imported
+
+- [OpenStreetMap](http://wiki.openstreetmap.org/wiki/Osm2pgsql) data based on the [ClearTables osm2pgsql style](https://github.com/ClearTables/ClearTables)
+- [OpenStreetMapData](http://openstreetmapdata.com/) split and simplified water polygons
+- [Natural Earth](http://www.naturalearthdata.com/)
+
+## Schema
+
+The vector data source is using zoom level views for each layer and contains useful functions.
+The PostgreSQL code can be found in `sql`.
+
+*TODO: Write import container*
