 - order electronic components, see BOM (Bill Of Materials) appendix below,
 - solder electronic components. {- assembly instructions here-}
 
 ## Firmware upload
-The process is the same as for others Arduinos:
+This process is same as for other Arduinos:
 - connect USB-> UART converter,
 - start Arduino IDE,

+- open the firmware {-link here-} file,
 - select board and MCU in the Tools menu (hint: we are using "mini" board with 328p MCU),
 - press the "Upload" button in the interface and "Reset" on the Arduino.
 
-For arduinos with old bootloader you need to update it. (Tools-> Burn Bootloader).<br>
-For successful compilation, you must have "SoftwareSerial", "OneWire" and "DallasTemperature" installed (see Tools -> Manage Libraries).<br>
-As a first try it's enough to simply upload firmware without any tunings. Think of it as of commercial closed-source controller, where you cannot change internal options.

 ## Self-tests
 QA tests are available to test the assembled board.<br>
