# Installation and configuration guide I assume that you have a basic understanding of XMPP and the the concept of a XMPP component / transport. If not, please get a book about Jabber or read the standards. transWhat is a XMPP transport. By this means it extends the functionallity of an existing XMPP server. It acts as a gateway between the XMPP and WhatsApp networks. It receives WhatsApp messages and forwards them to your XMPP client (and vice-versa). The implementation of transWhat is based on the [Spectrum 2](http://www.spectrum.im) framework and the [Yowsup 2](https://github.com/tgalal/yowsup) library to interface with WhatsApp. The following chart summarizes the involved components and the protocols they use to communicate. ## Prosody ### Installation I will not cover the installation of Prosody in this guide. Please look for some other tutorials on how to do that. ### Configuration The only important thing for us is the configuration of a XMPP component (Spectrum 2 in our case). See http://prosody.im/doc/components. Append the following at the end of `/etc/prosody/prosody.cfg.lua` Component "whatsapp.0l.de" component_secret = "whatsappsucks" component_ports = { 5221 } component_interface = "127.0.0.1" ## Spectrum 2 #### Installation Manual compile latest version from [Github](https://github.com/hanzz/libtransport). You can use the following guide: http://spectrum.im/documentation/installation/from_source_code.html. #### Configuration Create a new file `/etc/spectrum2/transports/whatsapp.cfg` with the following content: [service] user = spectrum group = spectrum jid = whatsapp.0l.de server = localhost password = whatsappsucks port = 5221 backend_host = localhost backend = /location/to/transwhat/transwhat.py users_per_backend = 10 more_resources = 1 admin_jid = your@jid.example [identity] name = transWhat type = xmpp category = gateway [logging] config = /etc/spectrum2/logging.cfg backend_config = /etc/spectrum2/backend-logging.cfg ## transWhat ### Installation Checkout the latest version of transWhat from GitHub: $ git clone git@github.com:stv0g/transwhat.git Install required dependencies: $ pip install --pre e4u protobuf python-dateutil - **e4u**: is a simple emoji4unicode python bindings - [**yowsup**](https://github.com/tgalal/yowsup): is a python library that enables you build application which use WhatsApp service.
