 Where /myclient.ovpn/ comes from your VPN provider and with the password "/freedombone/".
 ** Connecting two meshes over the internet via a VPN tunnel
-Maybe the internet exists, but you don't care about getting any content from it and just want to use it as a way to connect mesh networks from different geographical locations together. VPN configuration, pem and stunnel files exist within the home directory. Edit the configuration with:
+Maybe the internet exists, but you don't care about getting any content from it and just want to use it as a way to connect mesh networks from different geographical locations together.
 
-#+begin_src bash
-nano ~/client.ovpn
-#+end_src
-
-Edit the IP address or domain for the mesh that you wish to connect to within the /route/ command:
-
-#+begin_src bash
-route [mesh IP or domain] 255.255.255.255 net_gateway
-#+end_src
+In your home directory on a system connected via ethernet to an internet router you'll find a file called *vpn.tar.gz*. If you want another mesh to be able to connect to yours then send them this file and get them to uncompress it into their home directory also on an internet gateway machine. If they have an external IP address or domain name for your router then they will be able to VPN connect using the *Connect Meshes* icon. They should also forward port 653 from their internet router to the mesh gateway machine.
 
-Then you can connect to the other mesh with:
+#+BEGIN_CENTER
+[[file:images/mesh_connect.jpg]]
+#+END_CENTER
 
-#+begin_src bash
-cd /home/fbone
-sudo stunnel stunnel-client.conf
-sudo openvpn client.ovpn
-#+end_src
+You should create a new *vpn.tar.gz* file for every other mesh which wants to be able to connect to yours. If you are prompted for a password it is 'freedombone'.
 
-Using the password "/freedombone/". From a deep packet inspection point of view the traffic going over the internet will just look like any other TLS connection to a server.
+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/").
 
 At present video doesn't work reliably, but text and voice chat do work well.
 
+** Collaborative document editing
+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.
+
+#+BEGIN_CENTER
+[[file:images/mesh_cryptpad1.jpg]]
+#+END_CENTER
+
+To create a document click on the CryptPad icon. Depending upon the specifications of your system it may take a few seconds to load, so don't be too disturned if the browser contents look blank for a while. Select _Rich Text Pad_ and give yourself a username.
+
+#+BEGIN_CENTER
+[[file:images/mesh_cryptpad2.jpg]]
+#+END_CENTER
+
+If you have the chat system running you can then copy and paste the URL for your pad into the chat, and the other user can then open the link and edit the document with you. You can repeat that for however many other users you wish to be able to edit.
+
 ** Social Network
 
 Patchwork is available as a social networking system for the mesh. Like all social network systems it has a stream of posts and you can follow or unfollow other users. You can also send private messages to other users with end-to-end encryption.

 Routers are intended to build network coverage for an area using small and low cost hardware. You can bolt them to walls or leave them on window ledges. They don't have any user interface and their only job is to haul network traffic across the mesh and to enable peers to find each other via running bootstrap nodes for Tox and IPFS. Copy the image to a microSD card and insert it into the router, plug in an Atheros wifi dongle and power on. That should be all you need to do.

 It's better not to trust images downloaded from random places on the interwebs. Chances are that unless you are in the web of trust of the above GPG signatures then they don't mean very much to you.

 When you first boot from the USB drive the system will create some encryption keys, assign a unique network address to the system and then reboot itself. When that's done you should see a prompt asking for a username. This username just makes it easy for others to initially find you on the mesh and will appear in the list of users.

 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.

 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. <a href="https://en.wikipedia.org/wiki/Freifunk">Freifunk</a> works in a similar way.

If they have an external IP address or domain name for your router then they will be able to VPN connect using the <b>Connect Meshes</b> icon. They should also forward port 653 from their internet router to the mesh gateway machine.
