How do I subscribe to Scope Updates on Slack?
zur Deutschen Version
In the top left corner of the Slack app click on the name of your team (in the screenshot below it's "Scope")
Click "Manage apps" on the following website.
Either find the already integrated RSS app or add the RSS app.
Copy the RSS-URL of the desired box into "Add Feed" and select appropriate channel. The RSS URL of a box is always the box URL followed by "/feed". Example: http://thescope.com/netzwirtschaft/feed
