Describe your goals in a unifying statement which encompasses
the entirety of your project.

"A few hints":
  • Describe your project in a "nutshell". (Try to keep the mission statement
    under 25 words)
  • Understand exactly what your project is and what you are going to do.
    (This will help you write a clean and clear mission statement.)
  • Try to boil your project down to its simplest elements and try to explain
    those things in the mission statement.
