Sync side-loaded content between your Kindle and other devices
I read a lot of books on my kindle that I got from other sources, mostly Manning and O'Rielly, but these won't sync between my phone and my kindle. Only books purchased from Amazon will sync between devices. [Again](http://timbroder.com/2011/01/getting-it-onto-the- kindle.html), Calibre to the rescue. For this to work, the book must already exist on the kindle and be sold through Amazon. The example book I'm going to use is Version Control with Git. Add the book to your Calibre library Update any needed…
