First you will have to make a personal copy of the Monkeytype repository, also known as "forking". Go to the [Monkeytype repo](https://github.com/monkeytypegame/monkeytype/) and then click the "fork" button.

Change the corresponding hex codes to create your theme. Then, go to `./frontend/static/themes/_list.json` and add the following code to the very end of the file (inside the square brackets):
Make sure the name you put matches the name of the file you created (without the `.css` file extension). Add the text color and background color of your theme to their respective fields.
Once you have created your theme(s), you now need to create a pull request to the main Monkeytype repository. Go to the branch where you created your new theme on GitHub. Then make sure your branch is up to date. Once it is up to date, click "contribute".
