 ### Configuration
 
@@ -13,16 +13,11 @@ You have to choose this frontend in Spectrum 2 configuration file to use it:
 
 	[service]
 	frontend=slack
+	client_id=42132532467.11232153249
+	client_secret=cfdw9erw9ew0gew9gds0sa9wqd9f8d6a
 
+To obtain the `client_id` and `client_secret` values, you have to create new Slack application on [Slack website](https://slack.com/apps/build). You also have to setup Spectrum 2 Web Interface to allow Slack users to register the transport and configure it. While creating new Slack application, you also have to setup the `Redirect URI`. Spectrum 2 Web Interface expects the `Redirect URI` to be configured as `http://domain.tld/oauth2`. You can choose whatever domain you are running at, but you have to preserve the `/oauth2` location.
 
 ## Usage
 
-To use Slack 2 frontend with Spectrum2, you have to add new bot to your Slack team and get the API token. After that, you can use `spectrum2_manager` to set the API token:
-
-	$ spectrum2_manager localhost set_oauth2_code API_TOKEN use_bot_token
-
-Use the real JID of your Spectrum 2 instance instead of `localhost`. Use the API token provided by the Slack instead of `API_TOKEN`.
-
-Once you do that, Spectrum 2 will contact the Slack team's primary owner with instructions how to configure it.
-
-
+Once you setup Spectrum 2 with proper `client_id` and `client_secret`, you can register as new user in the Spectrum 2 Web Interface.
