cd ~

2) Create a file called .bash_profile

3) Add the following line (press i)

export PS1="$ "

4) Save the file (press Escape, type :wq and hit Enter)

5) Restart Terminal

You should now see something like this:

There are other ways you can configure the command prompt (for example, showing the current time), but I prefer to keep it simple.
