+**Introduction**
+
+Objective-C is a powerful, object-oriented programming language primarily used for macOS and iOS development. While Swift has largely replaced it in modern Apple development, Objective-C remains essential for maintaining legacy codebases and understanding the foundations of Apple's ecosystem. This guide will introduce the fundamental concepts of Objective-C, helping you get started.
+
+---
+
+### 1. Understanding Objective-C
+- Superset of C with object-oriented capabilities.
+- Uses Smalltalk-style messaging (`[object message]` syntax).
+- Supports dynamic typing and runtime decision-making.
+- Historically required manual memory management (before ARC).
+
+---
+
+### 2. Setting Up Your Environment
+- Install **Xcode** for macOS and iOS development.
+- Use **Command Line Tools** to compile and run Objective-C programs.
+- Verify installation using the `clang --version` command in the terminal.
+
+---
+
+### 3. Basic Syntax and Structure
+- Uses `@import` or `#import` to include frameworks.
+- `@autoreleasepool` manages memory automatically.
+- `NSLog` is used for logging output.
+- Uses pointers (`*`) for object references.
+
+---
+
+### 4. Variables and Data Types
+- Supports standard C types: `int`, `double`, `bool`, etc.
+- Common object types include `NSString`, `NSNumber`, and `NSArray`.
+- Uses `@` symbol for object literals (e.g., `@"string"`, `@42`).
+
+---
+
+### 5. Object-Oriented Programming in Objective-C
+- Classes are defined using `@interface` and `@implementation`.
+- Instance methods are prefixed with `-`, while class methods use `+`.
+- Uses dot notation for properties and `self` keyword within methods.
+- Message passing uses square brackets (e.g., `[object method]`).
+
+---
+
+### 6. Memory Management
+- Before **ARC (Automatic Reference Counting)**, developers used `retain`, `release`, and `autorelease`.
+- ARC automatically manages memory for objects.
+- Uses `strong`, `weak`, `copy`, and `assign` property attributes to control memory behavior.
+
+---
+
+### 7. Conclusion
+- Objective-C is still relevant for legacy projects and bridging with Swift.
+- Understanding Objective-C fundamentals helps when working with older Apple APIs.
+- Next steps: Learn about protocols, categories, and runtime features.
