+===== Hosting Provider =====
 The host I chose to use is use [[https://m.do.co/c/bb281f2fae53|DigitalOcean]] I've been using them for some years and I'm very happy with the service and pricing. They have many options and allow you to scale to your requirements including hosting in many geographic locations.
