This application is to help Computer Science students by providing them with a single resource for them to study and learn about important concepts, common languages, algorithms, data structures, etc.

• Category: Educational
• Mobile: A website is view only, app will allow users to use camera for posting pictures of notes or important information.
• Story: Allows students to work together and share helpful information which will make learning a more communal experience.
• Market: Anyone who is studying computer science or a related field, or just somebody who is interested in the subject.
• Habit: Users can post any new information, but there will be a vote and discussion system on new posts and how reliable or correct the information is. The app will also be populated by posts from the developer.
• Scope: The CS Cheat Sheet app will start out as just an app to help study Computer Science along with a forum for discussion. It could later grow to include other areas of study, and maybe live chat rooms to discuss topics and learn from eachother.
