So, I'm a little confused on how to securely store my email credentials using Figaro - am about to push my app up to production from development. Noted on the guide at https://github.com/laserlemon/figaro though I not know where to begin and end. I tried searching on stack overflow for a guide on this but found none. What steps should I take after installing Figaro to store said credentials in development, then push my app up to production? Thanks. p.s. I'm a beginner in Rails.
My Git is up at https://github.com/cheese1884/197451
Is Using Figaro and Secrets.yml to Manage Env Variables still relevant as of 2018?
