+
+## Introduction
+
+This is the QMK firmware repository for the ElongatePCN, compatible with revisions Beta and pre-Beta.
+
+The ElongatePCB is an Open-Hardware guidelines compliant PCB which files can be found at [this link](https://github.com/Gondolindrim/AElongate). Its designer and maintainer is [Gondolindrim](https://github.com/Gondolindrim).
+
+## PCB Documentation
+
+See the [AcheronDocs](https://gondolindrim.github.io/AcheronDocs/elongate/introduction.html) page for the ElongatePCB full documentation. You can also check the KiCad PCB files at the [Elongate GitHub repository](https://github.com/Gondolindrim/Elongate).
+
+Before using the files for personal or commercial use, please read the [Acheron Open-Hardware License V1.2](https://gondolindrim.github.io/AcheronDocs/license/license.html) under which the Austin PCB is published.
+
+## How to compile
+
+After setting up your build environment, you can compile the Austin default keymap by using:
+
+ make acheron/elongate: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).
