Convert text file into shell script?

This might be a very vague question and I apologize if it is but i am doing an exam tomorrow and one of the questions on the paper asks "What two things do you need to do to convert a text file with a list of UNIX commands into a shell script?". Any help would be greatly appreciated.
Update: Thanks Synful Visions! If you wouldn't mind could you write it out for me?
