Controls hello
Here's a code block:
void render_framebuffer(void) {
    SDL_UpdateTexture(framebuffer_texture, NULL, framebuffer, (int)(SCREEN_WIDTH * sizeof(uint32_t)));
    SDL_RenderTexture(renderer, framebuffer_texture, NULL, NULL);
    SDL_RenderPresent(renderer);
}
And the following is a block quote.
This is easy!
