 You have to replace `/var/www/gmi/` with the folder where you'd like to have gemtext files and `/var/www/gmi/.certificates/` with the folder where you'd like to have your certificates stored. You also have to have to replace `example.org` with your domain name and if plan to speak in a different language than english in your gemini space than you should replace `en-US` with your countries language code (for example de-DE or fr-CA).
