+#Setting up OpenGL(freeglut) in Visual Studio
+
+1. Download free glew and glut from [here](http://www.mediafire.com/file/cmlnr0pj0pyha5d/Glew_and_Glut.zip/file)
+2. Extract the files in a folder you desire.(you need the folder so never delete it unless you donot want to do opengl anymore)
+3. Open Visual Studio and create a C++ solution/project.
+4. Go to the properties of your project.

+5. Inside properties go to C/C++ and in additional include directories include the include folders from the files you dowloaded before.

+6. Go to general of linker section and in additional library directories include the lib folders from the files you downloaded before.

+9. Now copy the code and build your project and run it, then you are good to go.

+        glClear(GL_COLOR_BUFFER_BIT);

+          glVertex3f(0, 0.75, 0);
+
+        glEnd();
+
+        glFlush();

+        glutInitWindowPosition(80, 80);
+        glutInitWindowSize(400, 300);

+
+        glutDisplayFunc(display);
+        glutMainLoop();
