+# Overview of the Project 
+
+## What is OpenGL?
+
+OpenGL is a **graphics API**. API stands for *application program interface*. It makes it possible for us to use and access our GPU (Graphics Processing Unit).
+
+OpenGL is one of the many graphics APIs available in the market. Examples of a few others are:
+- Direct3D
+- Vulcan
+- Metal
+
+Fundamentally, OpenGL is a standard that essentially enumerates which functions should accept which parameters and carry out which tasks.
+
+One of the benefits of OpenGL over other graphics APIs is its cross-platform compatibility.
+### Modern vs Legacy OpenGL
+
+Legacy OpenGL
+
+- It was a set of presets.
+- Short and easy to use code.
+- Provides less control.
+
+Modern OpenGL
+
+- Provides greater control.
+- The use of shaders is the primary distinction between Modern and Legacy OpenGL.
+
+For our project, we will be using Modern OpenGL.
+
+## What is a Game Engine?
+
+Software frameworks that are primarily used for creating video games are called game engines, and they typically come with pertinent libraries built in.
+
+A game engine's function is to offer a collection of tools for visual development along with reusable software parts so that a game can be built.
+
+At [wikipedia page,](https://en.wikipedia.org/wiki/Game_engine) you may get comprehensive information regarding gaming engines.
+
+### What are Shaders?
+
+- It's a program, a code that runs on the GPU (Graphics Processing Unit).
+
+When we write code in C++ or Java it runs on the CPU but we are dealing with graphics so we have to move code from CPU to GPU because it will run faster on the GPU.
+
+- Shaders allow us to write code on the GPU.
+## Approach for the project
+
+Learning how to use git and github for this project's ease of collaboration would be the first step.
+
+To begin the project, we must first become familiar with the fundamentals of OpenGL and how to render simple visuals and shapes on a display using the various libraries included in Modern OpenGL.
+
+[We shall watch this playlist to understand the concepts of OpenGL, vertex buffers and shaders used to render various graphic designs on the screen.](https://youtube.com/playlist?list=PLlrATfBNZ98foTJPJ_Ev03o2oq3-GGOS2)
+
+[Documentation of the many Modern OpenGL functions will aid in our learning of these libraries more quickly and thoroughly.](https://docs.gl/)
+
+After understanding the concepts of OpenGL and the libraries it contains, we must learn how to implement these libraries to make a game engine.
+
+[This playlist will serve as a tutorial for us as we build a 3D game engine using the OpenGL principles we learned from the last playlist.](https://youtube.com/playlist?list=PLv8DnRaQOs5-TyYnF56YghOxQBNr1VVmF)
+
+We'll get started on the task at hand and implement the various libraries ourselves after studying how the major OpenGL libraries are implemented to create a 3D game engine and create a checkers/chess-style game.
+
+Since using Object Oriented Programming reduces effort and makes code more concise and less redundant, all of the code will be written in C++.
+
+## Overview of the project
+
+Our goal with this project is to create a game engine and design a game that is comparable to checkers or chess.
+
+To accomplish this, we need to understand the foundations of OpenGL libraries and how the API renders and displays images on the display using Vertex Buffers, Shaders, and other pre-built libraries. 
+
+Utilizing C++, the code will be implemented.
