 A Simple Contact Form developed in PHP with HTML5 Form validation. Has a fallback in JavaScript for browsers that do not support HTML5 form validation.
 
+## Containerized with Alpine based container
+
+Using techniques from https://github.com/hardware/rainloop
+
+The container adds ssmtp so you can set up a working config in /etc/ssmtp/
+for the outgoing mail.
+
