+
+## Step 4 : Add new firmware versions
+
+In your values.py file, add the firmware in this format. Use a [decimal to hex converter](https://www.rapidtables.com/convert/number/decimal-to-hex.html) to get the correct string to place after 0x.
+
+```CAR.MODEL: {
+    (Ecu.type, 0xAddress-converted-to-hex, 0xSub-address-converted-to-hex-'None'-if-0): [
+      b'fwVersion',
+      b'existingFirmware',
+    ],
+  },
+```
+Here is a filled out example for the Honda Civic. Notice the eps firmware from above is already in this list.
+
+```CAR.CIVIC: {
+    (Ecu.eps, 0x18da30f1, None): [
+      b'39990-TBA,A030\x00\x00',
+      b'39990-TBA-A030\x00\x00',
+      b'39990-TBG-A030\x00\x00',
+      b'39990-TEG-A010\x00\x00',
+    ],
+  },
+```
+Ensure that every single ecu has its firmware in this file.
