Help

My domain is:http://1313taxichandigarh.com/

I am new to this website Letsencrypt.org

I don’t know how to activate or enable SSL Certificate for my website free of cost.
I don’t know which command I need to run, my hosting provider is Godaddy.

I’d recommend the Getting Started page on the Let’s Encrypt site.
