-## Gateway mode and server mode
+![Spectrum 2 animation](/animation.gif)
 
-Spectrum 2 can work in two modes: Gateway mode and Server mode. This chapter describes differences betweeen those two modes. If you want to find out how to configure Spectrum 2 to run in gateway or server mode, read the Configuration part of this documentation.
+Spectrum 2 is an open source instant messaging transport. It allows users to chat together even when they are using different IM networks. It acts as a transport layer between the users as showed in the animation above.
 
-### Gateway mode
 
-Gateway mode represents the classic way how XMPP gateway works. You have to configure an external XMPP server (like Prosody or Ejabberd) to serve the subdomain you want to use for Spectrum 2 (for example "icq.domain.tld"). Spectrum 2 in gateway mode then connects the XMPP server as its component and users are able to find out "icq.domain.tld" in Service Discovery, register it and use it.
+## Spectrum 2 frontends and backends
 
-*Advantages:*
-* Users can use more legacy networks using single XMPP account (and using single TCP connection).
-* It's easy to extend existing XMPP servers using gateway mode.
+As it was already written above, Spectrum 2 supports multiple IM networks. Spectrum 2 distinguishes between **Frontend** and **Backend** networks.
 
-*Disadvantages:*
-* Passwords are stored (even in encrypted form) on server.
-* Roster (contact list) synchronization can be problematic, because it depends on the client user uses. This can be improved by usage of Remote Roster protoXEP.
-* You have to setup XMPP server and use database even if you only want to use Spectrum 2 as a tool to connect legacy networks using XMPP protocol.
+If some network is supported as **Frontend**, it means that Spectrum 2 allows its users to use this network to communicate with other users using the **backend** network.
 
-### Server mode
+#### Example
 
-In server mode, Spectrum 2 behaves as standalone server. User then logins legacy networks by logging XMPP account like this one: "my_msn_name%hotmail.com@msn.domain.tld".
+If you for example use **Slack** as a frontend and **IRC** as a backend, the Spectrum 2 users can add Spectrum 2 to their Slack team, join the IRC network and communicate with their friends on IRC network.
 
-*Advantages:*
-* Passwords are not stored on server.
-* Roster synchronization is easy, because Spectrum 2 acts as normal server.
-* If you want to use Spectrum 2 as wrapper between different networks, you don't need database or Jabber server as another layer.
-* Using SRV records you can easily run Spectrum 2 on different machines to scale it.
+## Supported frontends
 
-*Disadvantages:*
+Currently, following frontends are supported:
 
-* Clients have to support more accounts to connect more legacy networks (Therefore they will need have to use more TCP connections).
+* XMPP
+* Slack
 
-## Instance, main process and backends
-
-This chapter describes differences between Spectrum 2 instance, Spectrum 2 main process and Spectrum 2 backends.
-
-### Spectrum 2 instance
-
-In server mode, Spectrum 2 instance is single XMPP server. In gateway mode, it is single XMPP gateway. We can say these statements about Spectrum 2 instance:
-
-* One instance is defined by one configuration file (By default stored in `/etc/spectrum2/transports/`).
-* Spectrum 2 instance is represented to end user by its Jabber ID (for example icq.domain.tld).
-* Internally every Spectrum 2 instance consists of Spectrum 2 main process and Spectrum 2 backends.
-* One instance can run just one type of Spectrum 2 backend.
-
-### Spectrum 2 main process
-
-Spectrum 2 main process is the main process of Spectrum 2 instance.
-
-* Spectrum 2 main process is responsible for running Spectrum 2 backends and routing users' requests to proper backend.
-* By default the logs of Spectrum 2 main process are stored in `/var/log/spectrum2/$jid/spectrum2.log`.
-
-### Spectrum 2 backend
-
-Spectrum 2 backend is special application run by Spectrum 2 main process. The goal of Spectrum 2 backend is to handle users's sessions. Spectrum 2 main process can handle more Spectrum 2 backends, but all messages from single user are always handled by the same backend.
-
-One Spectrum 2 instance can run only one type of Spectrum 2 backend.
+## Supported backends
 
+* IRC
+* Twitter
+* Skype
+* XMPP
+* Facebook
+* MSN
+* Yahoo

+## Spectrum 2 frontends and backends
+
+Spectrum 2 supports multiple IM networks. Spectrum 2 distinguishes between **Frontend** and **Backend** networks.
+
+If some network is supported as **Frontend**, it means that Spectrum 2 allows its users to use this network to communicate with other users using the **backend** network.
+
+#### Example
+
+If you for example use **Slack** as a frontend and **IRC** as a backend, the Spectrum 2 users can add Spectrum 2 to their Slack team, join the IRC network and communicate with their friends on IRC network.
+
+This page contains the list of currently supported frontends with the basic information about them.
+
+### How to change frontends
+
+Frontends are switched in Spectrum 2 config file using the following option:
+
+Section| Option| Value
+-------|-------|------
+service|frontend|Name of the frontend.
+
+### List of frontends
+
+Name| Supported network

+## Install Docker
+
+At first you have to install Docker. This is very well described on the official [Docker Installation page](https://docs.docker.com/v1.8/installation/).
+
+## Pull the Spectrum 2 Docker image
+
+To download Spectrum 2 Docker image to your system, just run following command:
+
+	$ docker pull spectrum2/spectrum2
+
+You can also update Spectrum 2 using this command later.
+
+## Create directory for Spectrum 2 configuration files
+
+Now you have to decide where to store the configuration files for Spectrum 2. We will use `/opt/spectrum2/` in our example:
+
+	$ mkdir /opt/spectrum2
+
+## Create configuration file
+
+You can use following default configuration files as a starting place:
+
+* [XMPP Frontend - gateway mode](https://github.com/hanzz/spectrum2/blob/spectrum/src/sample2_gateway.cfg)
+* [XMPP Frontend - server mode](https://github.com/hanzz/spectrum2/blob/spectrum/src/sample.cfg)
+
+Download the configuration file you chose into `/opt/spectrum` directory you have created earlier and edit it as you want. Check the documentation and tutorials for configuration examples.
+
+Note that the configuration files must have `.cfg` file extension.
+
+## Start Spectrum 2
+
+To start Spectrum 2 on background using Docker, all you have to do is running following Docker command:
+
+	$ docker run --name="spectrum2" -d -v /opt/spectrum2:/etc/spectrum2/transport spectrum2/spectrum2
+
+It will start Spectrum 2 and load the configuration files from `/opt/spectrum`. It also gives the spawned container name `spectrum2`.
+
+## Checking the Spectrum 2 logs
+
+To check the Spectrum 2 logs, use following Docker command:
+
+	$ docker logs spectrum2
+
+## Stopping the Spectrum 2
+
+To stop the Spectrum 2 container, use following Docker command:
+
+	$ docker stop spectrum2
