+# Zlant
+
+![Zlant](https://i.imgur.com/Siz8qsL.jpg)
+
+A compact 40% inspired by the Plank with a staggered layout instead.
+
+Keyboard Maintainer: [Felipe Coury](https://github.com/fcoury)
+
+Hardware Supported: Zlant Prototype PCB
+
+Hardware Availability: Group buy soon
+
+Make example for this keyboard (after setting up your build environment):
+
+    make zlant:default
+
+See [build environment setup](https://docs.qmk.fm/build_environment_setup.html) then the [make instructions](https://docs.qmk.fm/make_instructions.html) for more information.
