FYI for those installing on Windows in particular -- here's a quick tip!
Many users may install Anaconda in a local folder (i.e. "C:\users\myname\") and some people may use spaces in those user names (i.e. "C:\users\first lastname"). If you are changing directories to a file structure like that on the command line, you'll need to use quotes around the path name to get to the proper place!
