+# Satan GH60 ISO-DE Layout with split backspace and right shift
+
+![Layout Image](https://i.imgur.com/a7znS69.jpg)
+
+## Default Layer
+This ISO-DE based layout has a split backspace. the left part is the actual backspace and the right parts serves as a FN key.
+The right shift is also split, with the right part serving as the del key.
