 Your users will have a dedicated folder under `./accounts`. Also, your root domain's website will be in `./accounts/yourdomain.tld`. New users can create accounts on `/api/accounts/new` and create new certificates on `/api/accounts/cert`. An easy-to-use sign-up tool is found on `/api/accounts`.

 ##### How can send emails to my users with my Gmail?
 
 > To use Gmail you may need to configure ["Allow Less Secure Apps"](https://www.google.com/settings/security/lesssecureapps) in your Gmail account unless you are using 2FA in which case you would have to create an [Application Specific](https://security.google.com/settings/security/apppasswords) password. You also may need to unlock your account with ["Allow access to your Google account"](https://accounts.google.com/DisplayUnlockCaptcha) to use SMTP.
