-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.
+Mastodon is a **free, open-source social network server** based on **open web protocols** like ActivityPub and OStatus. The social focus of the project is a viable decentralized alternative to commercial social media silos that returns the control of the content distribution channels to the people. The technical focus of the project is a good user interface, a clean REST API for 3rd party apps and robust anti-abuse tools.
 
-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)).

 ## 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
+**No vendor lock-in: Fully interoperable with any conforming platform**
+
+It doesn't have to be Mastodon, whatever implements ActivityPub or OStatus is part of the social network!
+
+**Real-time timeline updates**
+
+See the updates of people you're following appear in real-time in the UI via WebSockets. There's a firehose view as well!
+
+**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 short videos**
+
+Upload and view images and WebM/MP4 videos attached to the updates. Videos with no audio track are treated like GIFs; normal videos are looped - like vines!
