University student documentation edits

Hello! I am a university student taking a technical writing course. For one project we need to make suggested edits to repos on github. 
Please use the following suggestions at your discretion :)

- reduced use of word 'you' to increase formality of writing
- removed empty words to make documentation more concise 

Thank you for your time!
