+
+## Overview
+
+**STM32Cube** is an STMicroelectronics original initiative to ease developers' life by reducing efforts, time and cost.
+
+**STM32Cube** covers the overall STM32 products portfolio. It includes a comprehensive embedded software platform delivered for each STM32 series.
+   * The CMSIS modules (core and device) corresponding to the ARM(tm) core implemented in this STM32 product.
+   * The STM32 HAL-LL drivers, an abstraction layer offering a set of APIs ensuring maximized portability across the STM32 portfolio.
+   * The BSP drivers of each evaluation, demonstration or nucleo board provided for this STM32 series.
+   * A consistent set of middleware libraries such as RTOS, USB, FatFS, graphics, touch sensing library...
+   * A full set of software projects (basic examples, applications, and demonstrations) for each board provided for this STM32 series.
+
+Two models of publication are proposed for the STM32Cube embedded software:
+   * The monolithic **MCU Package**: all STM32Cube software modules of one STM32 series are present (Drivers, Middleware, Projects, Utilities) in the repository (usual name **STM32Cubexx**, xx corresponding to the STM32 series).
+   * The **MCU component**: each STM32Cube software module being part of the STM32Cube MCU Package, is delivered as an individual repository, allowing the user to select and get only the required software functions.
+
+## Description
+
+This **stm32-mw-usbpd-core** MCU component repository is one element **common to all** STM32Cube MCU embedded software packages, providing the **USBPD MCU Middleware** part.
