 `libray` is now installed to your path. In the future I'll add this package to pypi.
 
+## How do I use it?
+
+```
+A Libre (FLOSS) Python application for unencrypting, extracting, repackaging,
+and encrypting PS3 ISOs
+
+optional arguments:
+  -h, --help            show this help message and exit
+  -v, --verbose         Increase verbosity
+  -o OUTPUT, --output OUTPUT
+                        Output filename
+  -k IRD, --ird IRD     Path to .ird file
+
+required arguments:
+  -i ISO, --iso ISO     Path to .iso file
+```
+
+Rip a PS3 to .ISO with an appropriate blu-ray drive: https://rpcs3.net/quickstart (see "Compatible Blu-ray disc drives section"). 
+Then just feed the .ISO to libray which will try to download an IRD decryption file for your iso. 
+
+Example:
+
+```
+libray -i ps3_game.iso -o ps3_game_decrypted.iso
+```
+
+Then, if you want to feed it into RPCS3 just extract the contents of the .ISO:
+
+```
+7z x nfs_ps3_decrypted.iso
+```
+
+And move the resulting folders into the appropriate folder for RPCS3.
