 ## What is an Embedded System?
 
-[Making Embedded Systems](https://www.oreilly.com/library/view/making-embedded-systems/9781449308889/): An embedded system is a **computerized system** that is **purpose built for its application**.
+[ISO/IEC/IEEE 24765 Standard:](https://www.iso.org/obp/ui/en/#iso:std:iso-iec-ieee:24765:ed-2:v1:en)
 
-[Analog Devices](https://www.analog.com/en/design-center/glossary/embedded-system.html): An embedded system 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.
+> **computer system** that is **part of a larger system** and **performs some of the requirements of that system**. For example, a computer system
+used in an aircraft or rapid transit system.
+>
+> The hardware and software of an embedded system are usually **minimized** and **optimized** for **specific functions**. The embedded system includes at least one microcontroller, microprocessor or digital signal processor. The embedded system designed to optimize reliability, cost, size and power saving for applications.
 
-[Embedded Systems Glossary](https://barrgroup.com/embedded-systems/glossary-e): A combination of **computer hardware and software**, and perhaps **additional mechanical or other parts**, designed to perform a **dedicated function**. In some cases, embedded systems are **part of a larger system** or product, as in the case of an antilock braking system in a car.

 ## Roadmap
 
+The roadmap is divided into three main sections: **SOFTWARE**, **HARDWARE**, and **SOFT SKILLS**.
+
+The hardware and software sections overlap in many embedded job roles. Different job titles, such as "Embedded Software Engineer / Developer," "Firmware Engineer / Developer," and "Embedded Linux Software Engineer / Developer," tend to focus more on software. On the other hand, job roles like "Embedded Hardware Engineer" and "Hardware Design Engineer" primarily focus on hardware. Additionally, there are positions like "Embedded Systems Engineer" that require a good understanding of both hardware and software. It's crucial to understand that each company in the embedded industry may have specific requirements for a job role, regardless of its title.
+
+With this in mind, the roadmap is designed to cover topics necessary for an "Embedded Systems Engineer" role. If you are aiming for an embedded software position, you should focus more on software skills in the roadmap. Conversely, if you are interested in an embedded hardware job, you should prioritize hardware skills.
+
+In the embedded industry, all job roles require some soft skills, which cannot be acquired solely through reading or watching videos. Soft skills are developed through communication with others and facing various work challenges. Improving soft skills is not a one-size-fits-all approach. It varies depending on your individual characteristics and involves being aware of your own strengths and weaknesses. Enhancing these skills takes time and effort.
+
+**Remember that the emphasis on software or hardware skills may vary depending on the specific requirements of the company or job position.**

 ## History
 
 The idea of creating this roadmap came from [vazeri / Embedded-Engineering-RoadMap-2018](https://github.com/vazeri/Embedded-Engineering-RoadMap-2018) which was well designed but had some flaws and not updated for years.
