 ## PACs using chiptool
 
-Tested with the RP2040 SVD. Other SVDs might not work quite right yet.
+It is mainly used by [Embassy project][embassy] to generate PACs targeting
+Raspberry Pi RP2040 and RP2350, Atmel STM32-series and Nordic Semiconductor
+nRF5x-series microcontrollers. Other SVDs might not work quite right yet.
