+# STM32-base F0 template
+
+This repository contains a template for starting projects based on the STM32F0 series devices using the [STM32-base repository](https://github.com/ThomasGravekamp/STM32-base). The code found in this repository has been tested with a STM32F030x4 device.
+
+## Usage
+
+To use this template, clone the [STM32-base repository](https://github.com/ThomasGravekamp/STM32-base) either directly in this templates folder or create a symbolic link to it.
