# How to echobot with XMPP, BOSH, and Strophe
1. Setup ejabberd(http://www.ejabberd.im/) server and setup account [email protected]
NOTE: localhost should be enough. If you setup something else, make sure you add it at /etc/hosts like this
#/etc/hosts
127.0.0.1 localhost.local
NOTE: Also download Psi(http://psi-im.org/), and make sure you can connect to your ejabberd server.
2. Download strophe(http://code.stanziq.com/strophe/) and place it (eg: /Users/makoto/work/sample/strophejs-1.0)

Something else I found helpful along the way (as I had old stuff installed):
gem uninstall --install-dir /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/gems/1.8 rails
