+# ROG-Core
+
+rog-core is a utility for Linux to control many aspects (eventually) of the ASUS ROG laptops like the Zephyrus GX502GW.
+
+The laptop I currently have is the GX502RW and so I'll be using that for the basis of this app. If I get wireshark captures from others with different ROG laptops then I should be able to add something like laptop and feature detection.
+
+## Use
+
+Currently requires root for accessing the USB devices (so, sudo).
+
+Commands are given by:
+
+```
+rog-core <option> <command> <command-options>
+```
+
+Help is available through:
+
+```
+rog-core --help
+rog-core <command> --help
+```
+
+Some commands may have subcommands:
+
+```
+rog-core <command> <subcommand> --help
+```
