Suggestion for Documentation change RE Linux installs.

[SirGoodenough]

One thing i cannot remember on new installs and would be helpful for people doing Linux installations.
When you try to flash the user usually does not have permission to write to the usb ports. There's an error when the tasmotize button is pressed about permissions. They simply need to be added to the correct group to allow them access to the ports.

I suggest adding a note to Linux users that they need to do this to allow the user to access the serial port, or they need to run the program as root (which no one wants). This has worked for me on Debian and Ubuntu.

The device is most likely attached to user group dialout. Just add your user to the dialout group so you have appropriate permissions on the device.

sudo usermod -a -G dialout $USER
(You may need to logout and back in for the new group to take effect.)
