-## How to use IRDKit
+# How to use IRDKit

-IRDKit is a tool that allows direct use of LibIRD functionality from the command line interface. The basic usage is:
-```
-irdkit game.iso game.ird
-```
-For detailed usage, run `irdkit --help`
+IRDKit is a tool that allows direct use of LibIRD functionality from the command line interface.
+For full help instructions, run `irdkit help`
+
+## Creating ISOs
+
+For all options, run `irdkit help create`
+
+To create an IRD from an ISO, run `irdkit create game.iso`
+Multiple ISOs can be processed at once with `irdkit create game1.iso game2.iso`
+Or a whole directory of ISOs can be processed with `irdkit create ./ISO`, or recursively with `irdkit create -r ./ISO`
+
+The IRD will be created in the same folder as the ISO, with the same filename.
+A different IRD path and/or filename can be defined with `-o` or `--output=`
+
+### Key
+By default, IRDs will be created by pulling keys from redump.org
+A key can be manually provided with `-k` or `--key=`
+A key file can be provided with `-f game.key` or `--key-file=`
+A key from GetKey log file can be used with `-l game.getkey.log` or `--getkey-log=`
+
+### PIC
+By default, a PIC will be generated assuming a default layerbreak
+A layerbreak value can be provided with `-b` or `--layerbreak=`
+A PIC from a GetKey log file can be used with `-l game.getkey.log` or `--getkey-log=`
+
+## Printing info
+
+For all options, run `irdkit help info`
+
+To print info about an ISO or IRD file, run `irdkit info game.iso` or `irdkit info game.ird`
+The info can be printed to a file, e.g. `-o out.txt` or `--output=`
+The info can be formatted as a JSON with `-j` or `--json`
+To print all info in the IRD use `-a` or `--all`
+
+## Comparing IRDs
+
+For all options, run `irdkit help diff`
+
+To compare two IRDs, run `irdkit diff game1.ird game2.ird`
+The comparison can be printed to a file, e.g. `-o out.txt` or `--output=`
+
+## Renaming IRDs
+
+For all options, run `irdkit help rename`
+
+To rename an IRD (or folder of IRDs) according to a redump DAT, run `irdkit rename -d redump.dat game.ird`
+
+## Verifying with an IRD
+
+To verify that a folder containing files from a PS3 disc match the file hashes within an IRD, run `irdkit verify game.ird folder/of/files`
