-### Account ID:
+### Downloading data for new apps/games and defining extra account IDs:  
 The script uses public Steam IDs (in Steam64 format) of apps/games owners in order to query the required info, such as achievement data.  
 By default, it has a built-in list of public users IDs, and you can extend this list by creating a file called `top_owners_ids.txt` beside the script, then add each new ID in Steam64 format on a separate line.
