 If you can not pass strong integrity, you can try to enable build vars spoofing
 by creating a file `/data/adb/tricky_store/spoof_build_vars`.
 
+After doing that, TrickyStore will automatically generate an example config json
+inside `/data/adb/tricky_store/spoof_build_vars` on next reboot. Then you can manually
+edit your spoof config.
+
+Here is an example of spoof config:
+
+```json
+{
+   "manufacturer": "Google",
+   "model": "Pixel",
+   "fingerprint": "google/sailfish/sailfish:8.1.0/OPM1.171019.011/4448085:user/release-keys",
+   "brand": "google",
