Most networks should use the first-boot-wizard experience, so they don’t have to change by hand the settings. First boot wizards sets ap_ssid and apname_ssid in lime-community and hostname in lime-node. This is the minimum setup needed that make sense.
I’ve created a new issue to also allow setting the country code (https://github.com/libremesh/lime-packages/issues/699).
For networks with “hackers” to maintain it I think the most common parameters that are changed from the defaults are: domain and channel_5ghz and channel_2ghz.
Those that are curious to get the most out of the device and are adventurous can get into its configuration and play with configs as mentioned by @hiure and @SAn, but it is not required nor necessary (though you can do some manual improvements, but as the network grows those get harder to maintain, and it is always better to include them in the core feature of the device (that will try their best to be accessible with just the basic skills )).
BTW: Welcome @hiure to the forum, it is nice to read you!
One of those tasks that you mentioned as important that is only available to the advanced users is the firmware update, that can only be done over the command-line right now and is described on the releases pages: https://gitlab.com/librerouter/openwrt/-/releases/
There is a roadmap to work on a user friendly interface for this, but it has not been made public yet (still looking for support for it).
El mago @SAn! Querido amigo que bom esse espaço de compartilhamento!
Actually, I think the topic I wanted to create was not really the first steps with librerouter, since we have the first boot wizard and I didn’t consider it when I chose the title “first steps with librerouter”. Here at the community network we are not using the FirstBootWizard.
