Mesh networks are useful as a quick way to make a fully decentralised communications system which is not connected to or reliant upon the internet. Think festivals, hacker conferences, onboard ships at sea, disaster/war zones, small businesses who don't want the overhead of server maintenance, protests, remote areas of the world, temporary "digital blackouts", scientific expeditions and off-world space colonies.

You can also use the restart icon if you are within range of the mesh network but the /Chat/ and /Other Users/ icons do not automatically appear after a few minutes.
* Connecting to the internet
If you need to be able to access the internet from the mesh then connect one of the peers to an internet router using an ethernet cable, then reboot it. Other peers in the mesh, including any attached mobile devices, will then be able to access the internet using the ethernet attached peer as a gateway.

After connecting one peer to the internet you may need to reboot other peers in order to update their network configurations.

From a deep packet inspection point of view the traffic going over the internet between mesh gateways will just look like any other TLS connection to a server.
* Mobile devices (phones, etc)
To allow mobile devices to connect to the mesh you will need a second wifi adapter connected to your laptop/netbook/SBC. Plug in a second wifi adapter then reboot the system. The second adaptor will then create a wifi hotspot which mobile devices can connect to. The hotspot name also contains its local IP address (eg. "/mesh-192.168.1.83/").

To allow mobile devices to connect to the mesh you will need a second wifi adapter connected to your laptop/netbook/SBC. Plug in a second wifi adapter then reboot the system. The second adaptor will then create a wifi hotspot (the connection shown in green above) which mobile devices can connect to. The hotspot name also contains its local IP address (eg. "/mesh-192.168.1.83/").
On a typical Android device go to *Settings* then *Security* and ensure that *Unknown sources* is enabled. Also within *Wifi* from the *Settings* screen select the mesh hotspot. The password is "/freedombone/". Open a non-Tor browser and navigate to the IP address showing in the hotspot name. You can then download and install mesh apps.

On the ordinary internet the date and time of your system would be set automatically via NTP. But this is not the internet and so you will need to manually ensure that your date and time settings are correct. You might need to periodically do this if your clock drifts. It's not essential that the time on your system be highly accurate, but if it drifts too far or goes back to epoch then things could become a little confusing in regard to the order of blog posts.

The mesh system includes the ability to collaboratively edit various sorts of documents using CryptPad. CryptPad is an almost peer-to-peer system in that it is designed for a client/server environment but that the server aspect of it is very minimal and limited to orchestrating the connected clients. With CryptPad installed on each mesh peer it effectively enables peer-to-peer collaborative editing. Documents are ephemeral and forgotten unless they're exported or copy-pasted to permanent storage.
