 ## Usage
+```shell
+pbf2png [options] DIR
+```
+
 Use `pbf2png -h` for help. The parameters should be self-explanatory, except the
 `-M` - tile name mask parameter. It's only there because of the notoriously known
 design flaw in the Mapbox vector tiles specification - the missing zoom level
 in the tile data. To render a tile, a workaround that fetches the zoom level from
 the file name (or somewhere else) is required. The default mask(regular expression)
-is `([0-9]+).*` which should fit all common tile name schemes like $z-$x-$y.pbf.
+is `([0-9]+).*` which should fit all common tile name schemes like `$z-$x-$y.pbf`,
+`$z_$y_$x.mvt`, etc.
+
+## Styles
+See the QtPBFImagePlugin [documentation](https://github.com/tumic0/QtPBFImagePlugin#styles)
+for how to set the style used for rendering the tiles. For the default OpenMapTiles
+data schema and the default OSM-Liberty style nothing needs to be done.
