+# Roman's Layout
+
+There are four layers:
+
+- **BASE** is [Norman layout](https://normanlayout.info/).
+- **SYMB** for numbers and symbols.
+- **PLVR** is optimized for [Plover](http://www.openstenoproject.org).
+- **ARRW** for navigation (same fingers for arrows as HJKL on QWERTY).
+
+Looking for IJKL arrows? [Here we
+go](../romanzolotarev-norman-plover-osx/).
