+#### Bootloader
+
+The
+[bootloader](https://github.com/JF002/pinetime-mcuboot-bootloader/releases/tag/1.0.0)
+is run right before booting into InfiniTime.   
+It is easily recognizable with its white pine cone that is progressively drawn
+in green. It also displays its own version on the bottom (1.0.0 as of now).

+#### The firmware
+
+Well, it's InfiniTime :) 
+
+#### Recovery firmware
+
+The *recovery functionality* allows to load a [recovery
+firmware](https://github.com/InfiniTimeOrg/InfiniTime/releases/tag/0.14.1) from
+the external flash memory to recover the PineTime when the current firmware
+cannot boot anymore. 
+
+This recovery firmware is a slightly modified version of InfiniTime that only
+provides a basic UI and the OTA functionality. You'll be able to use this
+firmware to load a new firmware over-the-air using BLE connectivity.
+
+[This
+article](https://www.ncartron.org/pinetimes-infinitime-new-bootloader-and-a-recovery-firmware.html)
+describes how to upgrade your PineTime to benefit from this feature.
+
+PineTime units shipped after (confirm date with JF) come with the recovery
+firmware already installed, so there's no need to follow this procedure.

 ### Upgrading your PineTime
