Check out the full documentation on https://libremesh.org/development-network_profiles.html

Set of profiles for the networks using LibreMesh used by the firmware builder.

• Each community profile goes into a directory named as the community.
• Inside a community profile directory goes the devices profile, also split in directories
• The files available into community/device/root/ will be copied to the output firmware binary

The expected files to be into this repository are:

• Customized /etc/config/lime-community
• Set of scripts to configure/fix/add small specific stuff on the system in /etc/uci-defaults/
• SSH public keys from the community administrators in /etc/dropbear/authorized_keys
• Any other stuff you need to customize your own community network firmware

A special file named Makefile have to be placed in the device directory community/device/Makefile, see this file as an example. This file can also be used to include a list of extra packages which will be included in the firmware.
