Missing HTTPS/SSL certificate for Get-simple.info, Letsencrypt?

[c-base]

First, I appreciate the work you and the other volunteers have put into this project. Thank you for this.

Is there any way to access the [edit: get-simple.info] website over HTTPS?
I was hoping to see a SSL certificate when downloading GetSimple, to limit the chance of somebody tampering the .zip file & hack my website even before it is online..

What help would you need to get a Let's Encrypt SSL certificate implemented [edit: on get-simple.info ]?

Kind regards,
