+
+Litl is an easy to build 40% keyboard using only through hole components. It uses a separate microcontroller (like the Pro Micro or Elite C) to enable flexibility in connectivity and to further simplify the soldering experience (no more tricksy USB ports).
+
+* Keyboard Maintainer: [mohoyt](https://github.com/mohoyt)
+* Hardware Supported: litl, Pro Micro, Elite-C, Puchi-C, Nice!Nano
+* Hardware Availability: [sthlm kb](https://sthlmkb.com)
+
+Make example for this keyboard (after setting up your build environment):
+
+    make sthlmkb/litl:default
+
+See the [build environment setup](https://docs.qmk.fm/#/getting_started_build_tools) and the [make instructions](https://docs.qmk.fm/#/getting_started_make_guide) for more information. Brand new to QMK? Start with our [Complete Newbs Guide](https://docs.qmk.fm/#/newbs).
