 ## Overpass instance covering part of the world
 
-In this example the Overpass instance will be initialized with a planet file for Monaco downloaded from Geofabrik.
-Data will be stored in folder`/big/docker/overpass_db/` on the host machine and will not contain metadata as this example uses public Geofabrik extracts that do not contain metadata (such as changeset and user).
+As .osm.bz2 files are becoming increasingly rare, it is unfortunately often necessary to convert .osm.pbf files to .osm.bz2 files. This can be done either in a Docker container or on the host machine. Several examples of how to proceed are provided.

+Data will be stored in folder `/big/docker/overpass_db/` on the host machine and will not contain metadata as this example uses public Geofabrik extracts that do not contain metadata (such as changeset and user).
 Overpass will be available on port 12345 on the host machine.

+In this example the Overpass instance will be initialized with a planet file for Monaco. Since there are currently no download servers with the .osm.bz2 file format available you need to get the file on your own or use a solution below.
