+
+### Extracting assets
+1) Download the tools from the Releases panel on the right (or build them)
+1) Download the [psarc](http://www.mediafire.com/file/aegbgpkm3xfot80/psarc.zip/file) tool
+1) Go to your installed game's USRDIR directory (example: `rpcs3\dev_hdd0\game\NPUA80663\USRDIR`).
+   We'll now refer to this as `$USRDIR`.
+1) Copy `psarc.exe` there (or use the full path to it in the next command)
+1) Run:
+    ```cmd
+    mv Sly1.psarc Sly1.orig.psarc
+    psarc extract --input=Sly1.orig.psarc --to=.
+    ```
+1) Run:
+   ```cmd
+   sly_unpacker.exe $USRDIR/Sly1/SLY.WAC
+   ```
+   After a while you should see an `extracted/` dir in there, with all the games' files.
