-### 10pct scenario (`input/v6.3`)
+### 10pct scenario (`input/v6.4`)
 
-This scenario contains both 10pct and 1pct sample of the Greater Berlin population; road capacities are accordingly reduced. The scenario is calibrated taking into consideration the traffic counts, modal split and mode-specific trip distance distributions.

 1. Inside there, look for an `output-*` directory that you find interesting and go into that directory.
 1. Download `*.output_network.xml.gz` and `*.output_events.xml.gz`.  Best make sure that they do not uncompress, e.g. by "Download linked file as ...".
 1. Get these files into VIA.  This can be achieved in various ways; one is to open VIA and then drag the files from a file browser into VIA.
