+## 1. Introduction
+- It's a meta-build system generator.
+- How it works:
+    - We write high-level instructions in a CMakeLists.txt file (platform-agnostic).Then CMake generates build system files for the platform we choose:
+    - On Linux/Unix → generates Makefile (for make) or build.ninja (for ninja).
+    - On Windows → generates Visual Studio solutions (.sln).
+    - On macOS → can generate Xcode projects.
+
+## 2. Setup
+- Linux: Install: `sudo apt install cmake` , Verify: `cmake --version` 
+
+## 3. How to work with CMake
+
+1. Create CMakeLists.txt and resources file
+2. Run `cmake <dir-contain-CMakeLists.txt>` to set up & generate build system.
+3. Run `cmake --build <dir-contain-buildsystem>` to actually build/compile the project.
+4. Run the target build (e.g. `./targetName`)
+
+
+### 3.1. 
+> CMakeLists.txt
+```makefile
+cmake_minimum_required(VERSION 3.0)	// specifying a minimum CMake version
+project(CmakeprojectName)	// set the project name
+add_executeable(targetName "headerfile.h" "sourcefile1.cpp" "sourcefile2.cpp") // specified source code files
+```

 ## Introduction
+>It's a build tool (specifically, make is a build automation utility).
+How it works: Reads a file called Makefile that describes rules for how to build source files into targets (executables, libraries, etc.).
+
 GNU Make is a tool which controls the generation of executables and other non-source files of a program from the program's source files.
 Make get its knowledge of how to build your program from a file called the `makefile`, which lists each of the non-source files and how to compute it from the other files.
 When you write a program, you should write a makefile for it, so that it is possible to use Make to build and install the program.
