 +Vim’s design is based on the idea that a lot of programmer time is spent reading, navigating, and making small edits, as opposed to writing long streams of text. For this reason, Vim has multiple operating modes. 
 +  - Normal: for moving around a file and making edits 
 +  - Insert: for inserting text 
 +  - Replace: for replacing text 
 +  - Visual (plain, line, or block): for selecting blocks of text 
 +  - Command-line: for running a command

 +===== Commands =====
 +
 +Victoria's review: a minimal vim session experience:
 +
 +  - ''vim $filename'' -> opens a file in vim. If that file doesn't exist or you opened it in the wrong filepath, you will see an empty blank vim that says ''[NEW]'' at the bottom
 +  - ''i'' -> puts you in **i**nsert mode so you can freely type and move your cursor around. Says ''-- INSERT --'' in bottom left.
 +  - ''esc'' -> gets you out of insert mode
 +  - '':set nu'' shows you line numbers
 +
 +move around
 +  - ''0'' or ''Home'' puts your cursor to the beginning of the line (in command mode)
 +  - ''$'' or ''End'' puts your cursor to the end of the line (in command mode)
 +  - ''Shift + i'' puts your cursor to the beginning of the line and opens insert mode
 +  - ''Shift + a'' puts your cursor to the end of the line and opens insert mode
 +  - ''o'' opens insert mode on a new line below your cursor
 +  - up and down arrows move you up and down each line but to move between lines click ''g'' then up or down arrow
 +  - ''u'' undo last change (in command mode)
 +close vim temporarily
 +  * ''Ctrl + z'' puts the vim window to "sleep" and brings you back to the terminal
