 ### Step2: Use make to build
 
+Build all targets:
  - cd RemoteIDModule
  - make
 
+Or build specific targets (available targets: esp32s3dev, esp32c3dev, bluemark-db200, bluemark-db110, jw-tbd, mro-rid, jwrid-esp32s3, bluemark-db202, bluemark-db210, bluemark-db203, holybro-RemoteID, CUAV-RID):
+ - make esp32s3dev
+
 ### Step3: Use make to upload
 
+Upload default (ESP32S3_DEV):
  - cd RemoteIDModule
  - make upload
 
+Or upload specific build:
+ - make upload-ESP32S3_DEV
+
 If the board does not flash, hold-down the BOOT pushbutton on the PCB while pressing the RESET pushbutton briefly [to force it into bootloader mode] and retry.
 The ESP32-S3 is now running and emitting test/demo remote-id bluetooth
