+## Memfault demonstration (`double-tap-to-crash`)
+
+The builds with `double-tap-to-crash` to feature will crash when the button is
+double-tapped, meaning pressed in very short succession.
+
+Because there is not crash notification from Memfault, the backend needs to poll
+for the crash dump so it can show up quickly on the ThingyWorld dasboard.
+
+For this to happen, press the button **once** before double tapping. These
+builds are sending the button ID `42` which is the signal for the backend to
+scan for new crash reports for 120 seconds.
