-# Embedded-C-Fundamentals
+# Embedded C Fundamentals
 
-Fundamental C concepts, memory model, pointers, data structures, and embedded programming examples.
+Fundamental C concepts, memory model, pointers, data structures, and embedded programming examples.
+
+## Overview
+
+This repository contains notes, explanations, and runnable examples covering fundamental concepts of the C programming language commonly encountered in embedded software development.
+
+The goal is not to teach C from scratch.
+
+Instead, the focus is on understanding how things work under the hood and revisiting language features that are often hidden behind modern C++ abstractions.
+
+Topics are explored through small, self-contained examples that can be compiled, executed, modified, and studied.
+
+## Topics
+
+Planned topics include:
+
+* Memory layout
+* Variables and storage duration
+* Pointers
+* Arrays
+* Strings
+* Structures
+* Dynamic memory allocation
+* Function pointers
+* Linked lists
+* Bit manipulation
+* Volatile
+* Const correctness
+* Undefined behaviour
+* Memory-mapped I/O concepts
+* Common embedded programming patterns
+* Common interview questions
+
+## Repository Structure
+
+```text
+examples/
+notes/
+diagrams/
+interview_questions/
+```
+
+The structure may evolve as additional material is added.
+
+## Philosophy
+
+Understanding C is not about memorizing syntax.
+
+It is about understanding:
+
+* where data is stored
+* who owns memory
+* how pointers behave
+* what the compiler is allowed to do
+* where undefined behaviour begins
+
+Every topic should be supported by practical examples whenever possible.
+
+## Intended Audience
+
+This repository may be useful for:
+
+* Embedded software engineers
+* Firmware developers
+* C++ developers refreshing C fundamentals
+* Engineers preparing for technical interviews
+* Students interested in low-level programming
+
+## Building Examples
+
+Examples are intended to be compiled using standard toolchains available on Linux systems.
+
+Example:
+
+```bash
+gcc example.c -o example
+./example
+```
+
+Individual examples may provide additional build instructions.
