Hey! I found this by coincidence!
I had some marketing courses before (my first year in Uni!) But not anymore lmao
Anyway, I think the best way to promote anything you want nowadays is via social media! People spend their time on social media more than anything.
Make a publication and share it with your friends and family members and every goddamn person you know out there. Let them share it with their friends and family! I'm sure everything will go well for you. Best of luck!
