At the top of our main file is code to generate 3 dots to give a perspective on the scale of the UP, DOWN, LEFT, RIGHT commands.

Also please note that the version of manim we are using is known as the "community" version (which is supposedly easier to set up than the original version).
Use the script above to run a specific scene. Replace [sceneName] with the name of your class/scene that you want to generate/render. The -pqh is responsible for the quality of the video. For more in-depth explanations check the manim community documentations.
