 *** XChat
 If you are using the XChat client:
 
 *** Using with Android
 Install [[https://f-droid.org/][F-Droid]]
 
-Search for and install Xabber.
+Search for and install *Orbot* and *Conversations*.
 
 Add an account and enter your Jabber/XMPP ID and password.
 
-From the menu select *Settings* then *Security* then *OTR mode*.  Set the mode to *Required*.
+From the menu select *Settings* then *Expert Settings*. Select *Connect via Tor* and depending on your situation you might also want to select *Don't save encrypted messages*.
+
+From the menu select *Manage accounts* and add a new account.
 
-Make sure that *Check server certificate* is not checked.
+#+BEGIN_SRC bash
+Jabber ID: myusername@mydomain
+Password:  your XMPP password
+Hostname:  mydomain
+Port:      5222
+#+END_SRC
 
-Go back to the initial screen and then using the menu you can add contacts and begin chatting.  Both parties will need to go through the off-the-record question and answer verification before the chat can begin, but that only needs to be done once for each person you're chatting with.
+Then select *Next*. When chatting you can use the lock icon to encrypt your conversation. It's also going through Tor, so passive surveillance of the metadata should not be easy for an adversary.
 ** Tox
 Tox is an encrypted peer-to-peer messaging system and so should work without Freedombone. It uses a system of nodes which act as a sort of directory service allowing users to find and connect to each other. The Tox node ID on the Freedombone can be found within the README within your home directory. If you have other users connect to your node then you will be able to continue chatting even when no other nodes are available.
