+# rask's Pearl 40%
+
+## Layout
+
+The firmware offers five layers:
+
+1. Base layer
+2. Base with numbers and symbols (Fn1)
+3. Base with F-row and arrows (Fn2)
+4. Base with media and RGB controls (Fn3)
+5. More nav and utils (Fn2+Fn3, aka NavFn)
+
+![rask's Pearl 40% layout](https://i.imgur.com/gKVQapZ.png)
+
+Base for this firmware copied from jetpacktuxedo's QMK firmware.
+
+---
+
+## Compiling and flashing
+
+To compile a HEX follow the Pearl 40% instructions.
+
+Flashing instructions also available at Pearl 40% instructions.
