+:::info
+When uploading a custom firmware, it's recommended to create a single .bin file that contains the bootloader, partition table, and 
+application. You can use the [esptool merge_bin command](https://docs.espressif.com/projects/esptool/en/latest/esp32/esptool/basic-commands.html#merge-binaries-for-flashing-merge-bin) to create such file. 
+
+For ESP-IDF projects, you can also build a single UF2 file using the command: `idf.py uf2`. The file will be located in `build/uf2.bin`, and can be uploaded to the simulator.
