+## Get Started for INMP441, MAX98357a and FastLED
+- Set the device_type to 7 in the settings.ini
+- Configure pins on /devices/Inmp441Max98357aFastLed.hpp
+- Flash the esp32 using usb to uart converter
+- First flash, set "upload" as method under the OTA section in the settings.ini. After that you can set it to "ota" as well
+- Build and flash the project with PlatformIO, for example run `pio run --target upload` from the commandline
