+# VHP4Safety videos on SURF's PeerTube instance
+
+PeerTube is open source software for sharing videos, like project introductions, webinars, and 
+demos, and screenshots explaining how to use software. The Dutch SURF overs an PeerTube
+instance for use by Dutch higher education. VHP4Safety uses this platform to share videos.
+This document describes how you can watch these videos, but also how you can receive
+alerts when new videos show up.
+
+## Watching videos
+
+The simplest way to watch videos is to just visit our VHP4Safety channel at [https://video.edu.nl/a/vhp4safety/videos](https://video.edu.nl/a/vhp4safety/videos).
+That website looks something like this:
+

+
+You do not need an account and you do not need to accept any cookies that may track your
+online behavior. You can click a video and it will automatically start playing the video. You can
+pause or stop the video, change the speed, and customize your experience with various other
+common features you are used to:

+
+## Subscribing to the VHP4Safety videos
+
+If you like to get alerted about new videos on our PeerTube channel, there are two options.
+
+### Following via the fediverse
+
+If you have a fediverse account, e.g. Mastodon account via SURF's social.edu.nl platform,
+then you can just subscribe via the Subscribe button below the video and select
+`Subscribe with your local account`:

+
+Maybe easier, however, is to just follow directly from
+your fediverse client software, search for VHP4Safety profiles, and select the
+`@vhp4safety@video.edu.nl` account. In both cases, the next time our project posts a video,
+you get a message via the fediverse.
+
+### Following via a podcast or RSS feed
+
+If you prefer to have the videos show up in your podcast application or in your newsfeed
+application (for example [Feedly](https://feedly.com/)), then the PeerTube software provide two feeds:
+
+* [this podcast feed](https://video.edu.nl/feeds/podcast/videos.xml?videoChannelId=901)
+* [this RSS feed](https://video.edu.nl/feeds/videos.xml?videoChannelId=901)
+
+## Final notes
+
+We welcome all videos related to VHP4Safety. If your project video can be added too, please
