+If you would like to email your agenda to someone, you'll first need to setup SMTP. If you're using Gmail or Google Apps, make sure that you set your email account [to allow less secure apps](https://support.google.com/accounts/answer/6010255?hl=en). You can also use Amazon SES or other services with SMTP authentication to send mail. 
 
 Edit the configuration file with `daytimer config -e` or edit `~/daytimer/config.yml` with your email credentials:
 
 ```yaml
