+# PS4 Sflash0 NOR Dump Payload
+
+This payload was made for dumping NOR firmware (so called Sflash0) to USB drive instead using FTP.
+
+The compiled PS4 payload is available for download in the [release section](https://github.com/Andryshik345/ps4-sflash0-dumper/releases/).
+
+## How to compile for PS4
+
+1. Set up the PS4 payload SDK from https://github.com/Scene-Collective/ps4-payload-sdk.
+2. In the ps4-sflash0-dumper directory: `make clean && make` to compile.
