Multi-site setup virtual dirs

Just a beginner question:
I want to use multiple “sites” hosted on 1 domain organized with vdirs (domain/dir1, domain/dir2 etc) with one kirby installation using 1 theme for all sites. Can i do that with Multi-site setup and how can i do that, or is there another way to do this?
Thank you
