+## Why did you create PeerTube?
+
+We can't build a FOSS video streaming alternative to YouTube, Dailymotion,
+Vimeo... with centralized software. One organization alone may not have
+enough money to pay for bandwidth and video storage of its servers.
+
+Our stance is that only a decentralized network of servers can provide an
+acceptable answer to technical issues (bandwidth, transcoding expenses, etc.)
+and social answers (need for a particular moderation policy, preserving
+content, etc.).
+
+While a paragraph is not enough to answer all these problems, PeerTube has
+very early prouded itself for using a contributory design, both for creating
+communities as federated nodes (as [Mastodon](https://joinmastodon.org/) for
+example), and for seeding videos (instances can seed each other's videos). But it's not
+enough because one video could become popular and overload the server. That is
+why we need to use a P2P protocol to limit the server load. Thanks to
+[WebTorrent](https://github.com/feross/webtorrent), we can use BitTorrent
+inside most modern web browsers, and users become seeds as the video gets
+more viewers.

 You can't. You'll need to reinstall an instance and reupload your videos.
 
 
+## Why do we have to put our Twitter username in PeerTube configuration?
+
+You don't have to: we set a default value if you don't have a Twitter account.
+We need this information because Twitter requires an account for links share/videos embed on their platform.
+
+
+## How video views are calculated?
+
+Your web browser sends a view to the server after 30 seconds of playback. Then, the IP cannot send another view in the next hour.
+Views are buffered, so don't panic if the view counter stays the same after you watched a video.

 Not really. For instance, the demonstration server [https://peertube.cpy.re](https://peertube.cpy.re) has 2 vCore and 2GB of RAM and consumes on average:
