-## If nobody watch a video, is it seeded?
+## If nobody watches a video, is it seeded?
-Yes, the origin server always seeds videos uploaded on it through [Webseed](http://www.bittorrent.org/beps/bep_0019.html).
+Yes, the origin server always seeds videos uploaded on it thanks to
+[Webseed](http://www.bittorrent.org/beps/bep_0019.html).
## What is WebSeed?
-It is a BitTorrent extension that allow a server to seed a file through HTTP. It just need to serve statically a file, and then the clients will request chunks with a Content-Range HTTP header.

-## If a client requests each chunk of a video through HTTP, the server be overloaded!
+## If a client requests each chunk of a video through HTTP, will the server be overloaded?
-Not really. Reverse proxy like Nginx handle very well requests of static files. In my tests it can send chunks at 10MB/s without consuming more than 5% of CPU on a very small VPS.

-## An index of all videos of the network won't be too large for small servers?
+## Will an index of all the videos of servers you follow be too large for small servers?
-No, 1000000 videos will represent around 2GB on PostgreSQL. It is acceptable for a video platform.
+In our benchmarks, 1,000,000 videos takes around 2GB of storage on PostgreSQL.
+We think it is acceptable for a video platform.
-## What kind of videos can I upload?
+## What codecs can I use for the videos I want to upload?
WEBM, MP4 or OGV videos.
-## I want to change my host or move to HTTPS, how can I do?
+## I want to change my host, how can I do that?

+If you already have followers, you can't.
+
+If you don't have any followers, update your configuration and run
+`NODE_ENV=production npm run update-host` to update the torrent files (they contain your domain name).
+
+
+## Should I have a big server to run PeerTube?
+
+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:
+ * **CPU** -> nginx ~ 20%, peertube ~ 10%, postgres ~ 1%, redis ~ 3%
+ * **RAM** -> nginx ~ 6MB, peertube ~ 120MB, postgres ~ 10MB, redis ~ 5MB
+
+So you would need:
+ * **CPU** 1 core if you don't enable transcoding, 2 at least if you enable it
+ * **RAM** 1GB
+ * **Storage** Completely depends on how many videos your users will upload
-If you already have friends you need to quit them.
-Then, update your configuration and run `NODE_ENV=production npm run update-host` to update the torrent files.
