To use a custom `wg.conf` template, set the `WG_CONF_TEMPLATE` environment variable to a path to such file. To make sure `wireguard-ui` will be able to work with it - refer to the [default template](templates/wg.conf).
In order to send the wireguard configuration to clients via email, set the following environment variables:
- using SendGrid API
```
SENDGRID_API_KEY: Your sendgrid api key
EMAIL_FROM_ADDRESS: the email address you registered on sendgrid
EMAIL_FROM_NAME: the sender's email address
```
- using SMTP
```
SMTP_HOSTNAME: The SMTP ip address or hostname
SMTP_PORT: the SMTP port
SMTP_USERNAME: the SMTP username to authenticate
SMTP_PASSWORD: the SMTP user password
SMTP_AUTH_TYPE: the authentication type. Possible values: PLAIN, LOGIN, NONE
SMTP_ENCRYPTION: the encryption method. Possible values: SSL, SSLTLS, TLS or STARTTLS (default)
EMAIL_FROM_ADDRESS: the sender's email address
EMAIL_FROM_NAME: the sender's name
