-Mastodon is a free, open-source social network server. A decentralized solution to commercial platforms, it avoids the risks of a single company monopolizing your communication. Anyone can run Mastodon and participate in the social network seamlessly.
+So here's the deal: we all work on this code, and then it runs on dev.glitch.social and anyone who uses that does so absolutely at their own risk. can you dig it?
 
-An alternative implementation of the GNU social project. Based on [ActivityStreams](https://en.wikipedia.org/wiki/Activity_Streams_(format)), [Webfinger](https://en.wikipedia.org/wiki/WebFinger), [WebSub](https://en.wikipedia.org/wiki/WebSub) and [Salmon](https://en.wikipedia.org/wiki/Salmon_(protocol)).

-The project focus is a clean REST API and a good user interface. Ruby on Rails is used for the back-end, while React.js and Redux are used for the dynamic front-end. A static front-end for public resources (profiles and statuses) is also provided.

-## Features
-
-- **Fully interoperable with GNU social and any OStatus platform**
-  Whatever implements Atom feeds, ActivityStreams, Salmon, WebSub and Webfinger is part of the network
-- **Real-time timeline updates**
-  See the updates of people you're following appear in real-time in the UI via WebSockets
-- **Federated thread resolving**
-  If someone you follow replies to a user unknown to the server, the server fetches the full thread so you can view it without leaving the UI
-- **Media attachments like images and WebM**
-  Upload and view images and WebM videos attached to the updates
-- **OAuth2 and a straightforward REST API**
-  Mastodon acts as an OAuth2 provider so 3rd party apps can use the API, which is RESTful and simple
-- **Background processing for long-running tasks**
-  Mastodon tries to be as fast and responsive as possible, so all long-running tasks that can be delegated to background processing, are
-- **Deployable via Docker**
-  You don't need to mess with dependencies and configuration if you want to try Mastodon, if you have Docker and Docker Compose the deployment is extremely easy
-
