-# Working procedure for testing file transfer with aquatic_ws
-
-- On VPS, create identity (using real certificate), run tracker with TLS
-- On VPS, create torrent with external url as announce. Edit file and put
-  external url not only as announce, but in announce list too.
-- On VPS, disallow traffic to other trackers by adding them to /etc/hosts
-  or maybe with firewall, since webtorrent-hybrid adds its own trackers
-  willy-nilly. To get a list of the tracker urls which are actually used,
-  the node application under heading "Seed application" can be used as a
-  starting point.
-- I opened the listening port in the VPS firewall too (this might not be
-  necessary if running both clients on the VPS, see below)
-- On VPS, run webtorrent-hybrid download --keep-seeding ./abc.torrent
-- On desktop/non-VPS computer, fetch torrent file, run
-  webtorrent-hybrid download ./abc.torrent
-  I actually got it to work running this client on the VPS too.

-## Simplifications to procedure that might work
-
-- using fake certificate and routing certificate url to localhost in
-  /etc/hosts, meaning all of this could maybe be run locally/in Docker (but I
-  think sdp negotiations tend to fail in that case..)
-
-## Issues with Docker implementation
-
-- webtorrent-hybrid adds its own trackers when opening torrents, even if they
-  have been removed from file! The really robust way to get around this would
-  be to block all outgoing traffic with e.g. iptables before starting tests,
-  but I couldn't get it to work
-
-## Notes on testing locally
-
-Official tracker does not successfully handle file transfer on localhost
-on my machine between two instances of the official client (webtorrent-hybrid),
-probably due to sdp negotiation issues. This was with plain `ws` protocol.
-
-## Possibly useful collection of commands
-
-```sh
-npm install -g webtorrent-hybrid
-npm install -g bittorrent-tracker # Reference tracker
-
-bittorrent-tracker --ws -p 3000 & # Reference tracker
-
-mkdir files-seed files-leech torrents
-
-webtorrent create files-seed/ws-ipv4 --announce "wss://127.0.0.1:3000" > torrents/ws-ipv4.torrent
-
-cd files-seed
-webtorrent-hybrid seed torrents/ws-ipv4.torrent --keep-seeding -q &
-
-cd ../files-leech
-webtorrent-hybrid download torrents/ws-ipv4.torrent -q &
-```
