+# Janus Default Keymap
+
+![Janus default keymap image](https://i.imgur.com/7FevUIZh.png)
+
+The default Janus keymap is simple and organized. The only QMK special features used are layers and one shot keys for modifiers.
+
+It is inspired by [Callum's keymap](https://github.com/qmk/qmk_firmware/tree/master/users/callum), with a few differences:
+
+* Modifier keys are moved to the bottom row on every layer, and are mirrored on both sides.
+* Symbol layer only contains non-shifted symbol keys.
+* General differences in key positions.
+
+For simplicity's sake, the keymap uses QMK's native one shot key implementation. There are other excellent one shot implementations out there, including Callum's in the aforementioned keymap.
