+# Heimdall
+
+Heimdall is a cross-platform open-source tool suite used to flash firmware (aka ROMs) onto Samsung mobile devices.
+
+## Supported Platforms
+
+Officially, AMD64/x86-64 (64-bit) or x86 (32-bit) computers running:
+
+ * Linux
+ * macOS
+ * Windows (XP, Vista, 7 etc.)
+
+However, several third-parties have reported success running Heimdall on ARM chipsets
+(in particular Raspberry Pi), as well as additional operating systems such as FreeBSD.
+
+## How does Heimdall work?
+
+Heimdall connects to a mobile device over USB and interacts with low-level software
+running on device, known as Loke. Loke and Heimdall communicate via the custom
+Samsung-developed protocol typically referred to as the 'Odin 3 protocol'.
+
+USB communication in Heimdall is handled by the popular open-source USB library, [libusb](http://libusb.info).
+
+## Free & Open Source
+
+Heimdall is both free and open source. It is licensed under the MIT license (see LICENSE).
+
+Heimdall is maintained and predominantly developed by [Glass Echidna](http://glassechidna.com.au/),
+a _tiny_ independent software development company. If you appreciate our work and would like
+to support future development please consider making a [donation](http://glassechidna.com.au/donate/).
