 ### Troubleshoot
 
 If the command fails to upgrade the firmware, please make sure that:
 
 - Arduino IDE / AVRDUDE is installed.
-- That you are using a Windows/Mac/Linux machine (remember, this cannot be performed on a Chromebook).
+- That you are using a Windows/Mac machine (remember, this cannot be performed on a Chromebook).
 - That you have the `.hex` file in the Desktop folder. The command is written to look for it in that specific folder, so if it is not present, it will not work.
