+This guide mainly focuses on the steps to follow to submit an issue or a pull request.

-### 1. Before opening an issue
-Please check the following boxes before posting an issue:
- [ ] `Make sure you are using the latest commit (major releases are Tagged, but corrections are available as new commits).`
- [ ] `Make sure your issue is a question/feedback/suggestions RELATED TO the software provided in this repository.` Otherwise, it should be discussed on the [ST Community/STM32 MCUs forum](https://community.st.com/s/group/0F90X000000AXsASAW/stm32-mcus).
- [ ] `Make sure your issue is not already reported/fixed on GitHub or discussed on a previous issue.` Please refer to this [dashboard](https://github.com/orgs/STMicroelectronics/projects/5) for the list of issues and pull-requests. Do not forget to browse into the **closed** issues.
+## 1. Issues

-### 2. Posting the issue
-When you have checked the previous boxes. You will find two templates (Bug Report or Other Issue) available in the **Issues** tab of the repository ([link](https://github.com/STMicroelectronics/stm32_mw_usb_device/issues/new/choose)).

-## Overview
+## Overview of the STM32Cube MCU offer on GitHub

-**STM32Cube** is an STMicroelectronics original initiative to ease developers' life by reducing efforts, time and cost.
+**STM32Cube** is an original initiative by STMicroelectronics to **simplify** prototyping and development by **reducing** effort, time, and cost. It supports the entire ARM™ Cortex-based STM32 microcontroller portfolio and provides a **comprehensive** software solution including:
+  * The CMSIS Core and Device interfaces enabling access to processor core features and device-specific peripherals of STM32 microcontrollers.
+  * The STM32 HAL-LL drivers, an abstraction layer offering a set of APIs ensuring maximized portability across the STM32 portfolio.
+  * The BSP drivers enabling access to peripherals on the STM32 development boards, external to the microcontroller itself.
+  * A consistent set of middleware libraries offering standardized, high-level functionalities — such as USB, TCP/IP, file systems, and graphics.
+  * A full set of software projects (basic examples, applications, and demonstrations) that showcase specific functionalities or use cases, and provided with support for multiple IDEs.

-**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.
+The **STM32Cube embedded software** is available in two flavors:
+  * The **MCU Firmware** _monolithic_ offer, where **all** software components (Drivers, Middleware, Projects, Utilities) are included in a **single** repository for each STM32 series.
+  * The **MCU Software Components** _modular_ offer, where **each** software component (mainly Drivers and Middleware) is provided in a **dedicated** repository, allowing users to **select** only the components they need.

-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.
+The complete list of repositories is available [here](https://github.com/STMicroelectronics/STM32Cube_MCU_Overall_Offer/blob/master/README.md#content).

-## Description
+## Repository content

-This **stm32_mw_usb_device** MCU component repository is one element **common to all** STM32Cube MCU embedded software packages, providing the **USB Device MCU Middleware** part.
+This repository provides the STM32Cube **USB Device** Middleware Library, **common to every** STM32Cube MCU firmware that supports it.

-It represents ST offer to ensure the support of USB Devices on STM32 MCUs.
-It includes two main modules:
- * **Core** module for the USB device standard peripheral control APIs. It includes the files ensuring USB 2.0 standard code implementation for an USB device.
-These files’ APIs will be called within every USB device application regardless of the desired functionality.
- * **Class** module for the commonly supported classes APIs. it includes the files including different USB device classes. All STM32 USB classes are implemented according to the USB 2.0 and every class’s specifications. These files’ APIs will be called within USB device applications according to the desired functionality.
+This represents STMicroelectronics’ offering to support the USB Device role on STM32 MCUs. It includes two main modules:
+
+- **Core**: provides USB Device standard peripheral control APIs implementing the USB 2.0 standard code for a USB device. These APIs are called in every USB Device application, regardless of the desired functionality.
+
+- **Class**: provides APIs for commonly supported USB Device classes complying with USB 2.0 standard and their respective class specifications. These APIs are called in USB Device applications based on the desired functionality.

-# Purpose
-
-The USB device library comes on top of the STM32Cube™ USB device HAL driver and
-offers all the APIs required to develop an USB device application.
-
-The main USB device library features are:
