Changes

* Unix/Linux characters are '''case sensitive'''. It is recommended to be consistent (e.g. use all lowercase letters)* Adopt a '''consistent directory naming scheme ''' – this will help you to navigate within your directory structure later* Make your directory names '''meaningful'''* '''Avoid non-alphanumeric characters''', as they may have a special meaning to the system that will make your work more difficult when changing to directories, etc.* '''Avoid using spaces in ''' for directory names – consider periods, hyphens, and underscores instead
