+Email configuration
+===================
+
+User settings
+-------------
+
+To receive email notifications, users of Kanboard must have:
+
+- Activated notifications in the settings page
+- Have a valid email address in their profile
+
+Server settings
+---------------
+
+By default, Kanboard will use the bundled PHP mail function to send emails.
+Usually that require no configuration if your server can already send emails.
+
+However, it's possible to use other methods, the SMTP protocol and Sendmail.
+
+### SMTP configuration
+
+Create a blank `config.php` file or use the template `config.default.php` and set those values:
+
+```php
+// We choose "smtp" as mail transport
+define('MAIL_TRANSPORT', 'smtp');
+
+// We define our server settings
+define('MAIL_SMTP_HOSTNAME', 'mail.example.com');
+define('MAIL_SMTP_PORT', 25);
+
+// Credentials for authentication on the SMTP server (not mandatory)
+define('MAIL_SMTP_USERNAME', 'username');
+define('MAIL_SMTP_PASSWORD', 'super password');
+```
+
+### Sendmail configuration
+
+By default the sendmail command will be `/usr/sbin/sendmail -bs` but you can customize that in your config file.
+
+Example:
+
+```php
+// We choose "sendmail" as mail transport
+define('MAIL_TRANSPORT', 'sendmail');
+
+// If you need to change the sendmail command, replace the value
+define('MAIL_SENDMAIL_COMMAND', '/usr/sbin/sendmail -bs');
+```
+
+### The sender email address
+
+By default, emails will use the sender address `notifications@kanboard.net`.
+It's not possible to reply to this address.
+
+You can customize this address by changing the value of the constant `MAIL_FROM` in your config file.
+
+```php
+define('MAIL_FROM', 'notifications@kanboard.net');
+```
+
+That can be useful if your SMTP server configuration doesn't accept the default address.
+
+
+### Check for due tasks
+
+Every day, Kanboard can check for due tasks, to do that you have to setup a cronjob on your server and use the Kanboard command line interface.
+
+Here a example:
+
+```bash
+# Everyday at 8am we check for due tasks
+0 8 * * *  cd /path/to/kanboard && ./kanboard send-notifications-due-tasks >/dev/null 2>&1
+```
