 ## Installation

 ```
 $ go get github.com/whyrusleeping/ipfs-key
 ```
 
 ## Usage
+
+When run, it will write the bytes of
+the serialized private key to stdout. By default, a 2048 bit RSA key will be
+generated. In this case the key size can be changed by specifying the `-bitsize`
+option. The key type can be changed by specifying the `-type` option (rsa or
+ed25519). Currently only the RSA uses the -bitsize option.

 ```
-$ ipfs-key -bitsize=4096 > my.key
+$ ipfs-key -bitsize=4096 > my-rsa4096.key
+$ ipfs-key -type=ed25519 > my-ed.key
