+
+## Introduction
+
+This repo adds the support of STM8 architecture in Arduino IDE.<br>
+
+This porting is based on several external components :
+* STMicroelectronics Standard Peripheral Libraries (SPL)
+  * [SPL for STM8L](https://www.st.com/en/embedded-software/stsw-stm8016.html)
+  * [SPL for STM8S](https://www.st.com/en/embedded-software/stsw-stm8069.html)
+* Cosmic compiler, allowing to compile c++ source code on stm8 family (http://www.cosmic-software.com/)
+
+For now, the solution is running on Windows only.
+
+## Getting Started
+
+This repo is available as a package usable with [Arduino Boards Manager](https://www.arduino.cc/en/guide/cores).
+
+Use this link in the "*Additional Boards Managers URLs*" field:
+
+https://github.com/stm32duino/BoardManagerFiles/raw/master/STM8/package_stm8_index.json
+
+For full instructions on using the "**Boards Manager**", see the [Getting Started](https://github.com/stm32duino/wiki/wiki/Getting-Started) page.
+
+For advanced user, you can use the repository: see the [Using git repository](https://github.com/stm32duino/wiki/wiki/Using-git-repository) page.
+
+## Boards available
+  * STM8L
+    * [Nucleo STM8L152R8](https://www.st.com/en/evaluation-tools/nucleo-8l152r8.html)
+
+  * STM8S
+    * [Nucleo STM8S208RB](https://www.st.com/en/evaluation-tools/nucleo-8s208rb.html)
+
+
+## Troubleshooting and known issues
+
+Please note that this is a new core using a new compiler. You may face some issues with libraries compatibility.<br>
+We have several known issues :
+ * Windows 10:
+ *Board binary may be corrupted when plugged on a Windows 10 machine.
+    To ensure compatibility with Windows 10, please upgrade STLink with revision 2.32.22 or higher (estimated availability October 1st).*
+ * Endianness:
+ *STM8 microcontrollers are natively Big Endian whereas Arduino boards and STM32 microcontrollers are Little Endian.
+	By default, some libraries don't handle endianess, therefore these won't be directly compatible with STM8 (this is the case of SD library for example).*
+
+If you have any issue, you could [file an issue on Github](https://github.com/stm32duino/Arduino_Core_STM8/issues/new).
+
+If you have a question about compiler, you can also send a mail to Cosmic support : [send a mail to Cosmic support](mailto:support@cosmic.fr)
