I'd recommend that you tag the post with #hacktoberfest as well, and set up a number of issues on the repo also tagged with "hacktoberfest", as well as "help wanted". If the issue is easy and can be described i great detail what needs to be done, it should also be marked with "first-timers-only" or similar.
This gives you visibility in the community, gets you a lot of help, and possibly some permanent contributors :)
Thanks a lot for the comments! I will do so :)
