Hey, I'm Etcher!
Etcher is a free tool for flashing microSD card with the operating system images for Raspberry Pi single board computers. The user interface of Etcher is simple and it is really easy to use. It is a must have tool if you’re working with a Raspberry Pi project. I highly recommend it. Etcher is available for Windows, macOS and Linux. So you get the same user experience no matter which operating system you’re using.
