@@ -17,7 +23,7 @@ This porting is based on several external components :
   * [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.

@@ -50,7 +60,5 @@ We have several known issues :
  *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).
