+Installation
+------------
+
+The easiest way to install is to run the command:
+```
+pip install 'git+https://git.code.sf.net/p/ed448goldilocks/code#egg=edgold&subdirectory=python'
+```
+
+Usage
+-----
+
+This wraps the Ed448 code into a simple to use class, EDDSA448.  The
+easiest way to geenrate a new key is to use the generate class method.
+
+Example:
+```
+from edgold.ed448 import EDDSA448
+
+key = EDDSA448.generate()
+privkey = key.export(key('raw')
+msg = b'This is a message to sign'
+sig = key.sign(msg)
+
+pubkey = key.public_key().export_key('raw')
+key = EDDSA448(pub=pubkey)
+key.verify(sig, msg)
+```
