+4.3.3 The mfg_tool Example
+~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+In Espressif Matter Prep-provisioning modules, the DAC key pair, DAC and PAI certificates are pre-flashed by default.
+
+This section gives some examples on how to generate factory partition binary which includes :
+    | **Device unique data** (Discriminator, Verifier, Serial Number, etc)
+    | **Manufacturing information** (Vendor name, Product name, Hardware version, etc)
+
+**Note:** the items listed in the examples are all mandatory, some common manufacturing information could be removed if they are hard coded in the firmware.
+
+This is the example to generate factory images after pre-provisioning:
+
+- **Generate generic factory image**
+- ./mfg_tool.py -cd ~/test_cert/CD/Chip-CD-131B-1000.der -v 0x131B --vendor-name ESP -p 0x1000 --product-name light --hw-ver 1 --hw-ver-str v1.0 --mfg-date 2022-10-25 --passcode 19861989 --discriminator 601 --serial-num esp32c_dev3
+
+- **Generate multiple generic factory images**
+- ./mfg_tool.py -n 10 -cd ~/test_cert/CD/Chip-CD-131B-1000.der -v 0x131B --vendor-name ESP -p 0x1000 --product-name light --hw-ver 1 --hw-ver-str v1.0 --mfg-date 2022-10-25
+
+- **Generate factory image with rotating device unique identify**
+- ./mfg_tool.py -cd ~/test_cert/CD/Chip-CD-131B-1000.der -v 0x131B --vendor-name ESP -p 0x1000 --product-name light --hw-ver 1 --hw-ver-str v1.0 --mfg-date 2022-10-25 --passcode 19861989 --discriminator 601 --serial-num esp32c_dev3 --enable-rotating-device-id --rd-id-uid c0398f4980b07c9460f71c5421e1a3c5
+
+- **Generate multiple factory images with csv and mcsv**
+- ./mfg_tool.py -cd ~/test_cert/CD/Chip-CD-131B-1000.der -v 0x131B --vendor-name ESP -p 0x1000 --product-name light --hw-ver 1 --hw-ver-str v1.0 --enable-rotating-device-id --mfg-date 2022-10-25 --csv mfg.csv --mcsv mfg_m.csv
+
+- **The example of csv and mcsv file**
+- CSV:
+    | serial-num,data,string
+    | rd-id-uid,data,hex2bin
+    | discriminator,data,u32
+
+- MCSV:
+    | serial-num,rd-id-uid,discriminator
+    | esp32c_dev3,c0398f4980b07c9460f71c5421e1a3c5,1234
+    | esp32c_dev4,c0398f4980b07c9460f71c5421e1a3c6,1235
+    | esp32c_dev5,c0398f4980b07c9460f71c5421e1a3c7,1236
+    | esp32c_dev6,c0398f4980b07c9460f71c5421e1a3c8,1237
+    | esp32c_dev7,c0398f4980b07c9460f71c5421e1a3c9,1238
