-### Linux and Arduino Environment on Portenta X8
+### Portenta X8: Linux & Arduino Integration
 
 The Portenta X8 runs a **Yocto** based Linux distribution. It allows users to upload sketches to the M4 core of the STM32H7 using the Arduino IDE. The process of uploading sketches may seem familiar to Arduino users, but on Portenta X8, the system uses a service called `monitor-m4-elf-file.service`.
