 # pwgen
 Another of those passphrase generators
+
+The functionality is heavily inspired by [HSXKPasswd](https://github.com/bbusschots/hsxkpasswd), but it didn't quite have the functionality I wanted (random capitalization) and I wanted a python module for a possible future uwsgi webapp...
+
+# Why
+Because Randall Munroe says so.
+
+![alt text][xkcd]
+[xkcd]: http://imgs.xkcd.com/comics/password_strength.png
+
+# Requirements
+Python 2 or 3 as well as myspell-dictionaries for the language(s) you want to use.
+
+# What
+A password/passphrase generator. See below for some example usage.

+```
