Currently, when entering epic mode the README is frozen in the last level of the tower. When you're trying to fine-tune the score for a level other than the last one, it would be helpful if we had the README for that level available. The proposal is that when entering epic mode, the README is updated with all levels, one following the other.

Example:

# Starbolt - beginner

When entering a repository path, users should be able to hit TAB for autocomplete, like in bash.

/tmp/ has been hard coded in some instances

This will be replaced with https://docs.python.org/3/library/tempfile.html which has been well implemented in some instances in the code.

Q15. How can you use the promise API with a callback-based function like child_process.exec?

• new Promise(child_process.exec())
• util.promisify(child_process.exec())
• util.promisify(child_process.exec)
• new Promise(child_process.exec) <<<<----Correct

I believe the correct answer should be the 3rd one.
util.promisify(child_process.exec)

Currently the code coverage is around 70%. Need help to write tests so as to obtain a code coverage above 90%
