## Manual additions to config.txt
The `RPI_EXTRA_CONFIG` variable can be used to manually add additional lines to
the `config.txt` file if there is not a specific option above for the
configuration you need. To add multiple lines you must include `\n` separators.
If double-quotes are needed in the lines you are adding you can use single
quotes around the whole string.
For example, to add a comment containing a double-quote and a configuration
option:
RPI_EXTRA_CONFIG = ' \n \
# Raspberry Pi 7\" display/touch screen \n \
lcd_rotate=2 \n \
'
