1. Get a valid CDWserver Pro license key, save it as @CONFIGDIR@/key.txt on the server and make sure that only the user "@USER@" can read it by
    chown @USER@.@GROUP@ @CONFIGDIR@/key.txt
    chmod 400 @CONFIGDIR@/key.txt
    
  2. Important: Make sure your system clock is valid.
  3. Visit the "About" page to check the active license.
