The basic structure of the Asteroids game has been set up in the `index.html` file. It includes a canvas element for the game graphics and a script section for the game logic. The game features a vector ship, asteroids, bullets, score, and lives. Further implementation of game mechanics and graphics rendering will be done in the JavaScript section of the file.
