Manual Set up for hosted server

I have a site hosted with host gator. I haven’t found the manual instructions to get the cert and to the install to my site. If this is a duplicate post please direct me to the answer

For shared hosts, you’re at the mercy of the provider. See this answer.

Use this Command

./letsencrypt-auto --agree-dev-preview --server \ certonly -a manual

Enter the Domains in GUI manually or use -d domain-name
