 # Embedded Systems Engineering Roadmap
 
-This is a roadmap for those who want to build a career as an Embedded Developer or Embedded Engineer.
-In order to assist beginners, steps have been taken to create a roadmap that is straightforward and easy to understand.
+This roadmap is designed to assist beginners aspiring to build a career as an Embedded Engineer / Developer. To provide comprehensive guidance, I have carefully selected the topics based on current open job requirements and organized them according to my personal experience.
 
-If you think that this map can be improved in anyway, please start an issue or pull request. I’ll be maintaining and updating this repository frequently.
+Becoming an embedded engineer requires a broad understanding of both software and hardware. If you are starting on this journey, you must be highly motivated and passionate to pursue this path. The field of embedded systems demands a solid understanding of hardware functionality. But, as the well-known saying goes, "Hardware is hard!". So, patience and passion are the essential qualities that will help you overcome the various challenges encountered along this journey.
 
-The source file is created using [Microsoft Visio](https://office.com/visio) in `.vsdx` format and included in this repository for your contributions. If you do not have Microsoft Visio or you want to use free software, you can use [draw.io](https://draw.io) which can import and export `.vsdx` files.
+## What is an Embedded System?
 
-![Embedded Systems Engineering Roadmap](https://github.com/m3y54m/Embedded-Engineering-Roadmap/releases/download/Rev.I-2023-07-29/Embedded-Engineering-Roadmap.png)
+An [***embedded system***](https://www.analog.com/en/design-center/glossary/embedded-system.html) is a system in which the **computer** (generally a microcontroller or microprocessor) is included as an integral part of the system.
+
+Often, the computer is relatively **invisible to the user**, without obvious applications, files, or operating systems. Examples of products with invisible embedded systems are the controller that runs a microwave oven or the engine control system of a modern automobile.

+
+#### 🕹️ Arduino
+
+If you do not have any background in programming embedded systems, Arduino boards and libraries are the best choice for you to start and learn the basics. Just keep in mind that most of the Arduino libraries are developed only for learning purposes and are not are not optimized to be used in industry. Additionally, the Arduino takes care of most of the low-level operations and manipulation of registers that you, as an embedded engineer, should be able to handle yourself. If you want to become a professional embedded developer, you must be able to effectively use industry-standard APIs and frameworks provided and approved by microcontroller vendors. For example, CMSIS for ARM Cortex, STM32Cube for STM32, ESP-IDF for Espressif microcontrollers, etc.
