 # typeprint.py
 
-A terrible python script to output the contents of a file as if it were being typed by one of the l33t hack3rs you get in films. I made this because vypr's [typeprint](http://github.com/vypr/typeprint) didn't have an easy way to change the speed of output.
+Python script to print text/files character-by-character, originally intended for a retro terminal emulator.
 
 # Usage
 
 ```
-typeprint.py --ifile <input file> --speed <1 - 5>
+typeprint.py [-f|--file] [-s|--speed] <speed> <input>
 ```
+* `--speed`: specifies interval between each printed character.
+* `--file`: specifies `<input>` is a file, not text.
