"Here at resin.io we have thousands of users working through our getting started process and until recently we were embarassed about the steps that involved burning an SD card. There was a separate track for each Mac/Windows/Linux and several manual and error-prone steps along the way.
"To our surprise there was nothing out there that fitted our needs. So we built Etcher, a SD card burner app that is simple for end users, extensible for developers, and works on any platform." from the Etcher.io website.
