Have you read the included README file that would be installed with Splunk for Snort? Also it would seem you have confused the two separate authors of two separate Splunk apps. Please also direct your queries pertaining to the relevant app (in this case Splunk for Snort which you have downloaded), to the relevant questions area (Splunk for Snort) and not across multiple questions areas. If all else fails, then contact the author (Patrik Nordlen) of Splunk for Snort https://splunkbase.splunk.com/apps/#/author/patrik .
If you have installed Snort for Splunk, then I can help you by directing you to the README file contained in the app.
