How do I secure my website?

I just made a website that I got online with Heroku. I bought a domain on, and the website is up and working, but it is not secure (i.e. I cannot do I then bought an SSL Certificate for the year on Namesilo, but I do not know how to use this on my website? I’m really new to this, has anyone ever secured a site on namesilo before?

EDIT: Decided to abandon this and instead hosted the site on GitHub. I was using Flask on my website, but I realized it was totally useless as my site is actually completely static, so I removed all the Python and was able to move to GitHub and didn’t have to pay for anything (besides the domain, which I already have).
