i want to create an opengl game and i'm not sure how i'm going to start with opengl

i use visual studio code and manjaro kde linux

There are many resources that are cost-free. Some examples are http://www.opengl-tutorial.org/​ and https://learnopengl.com/​​

Make sure that the tutorials that you read and use are compatible with OpenGL 3 or 4. OpenGL 1 and 2 are still supported by most driver manufacturers, to keep old software from breaking, but they are not quite the same as version 3 or 4. Some parts of version 3 or 4 are a little more complicated than in version 1 or 2, but it's not all that bad.

@taby yo thanks
