@@ -2,23 +2,43 @@ The [WebTorrent](https://webtorrent.io) project provides a way for websites to
 share the bandwidth load with the users viewing content. It works on almost any
 content, but the first thing I I implemented is for Video.
 
+# Getting Media
+
+This demo is found in `admin/bando/demos/WTVideos.svelte` and it is coded to expect a sample image, video and torrent file at:
+
+* `/images/sample_video.mp4`
+* `/images/sample_image.jpg`
+* `/images/sample_video.mp4.torrent`
+
+If you want it to work locally, grab a video and an image and place them there, then use `mktorrent` as described next.
+
+# Making the .torrent
+
 This will most likely *only* work if you have your server on `127.0.0.1` since the torrent file is configured for that.  Also, the default `npm run dev` will run the simple tracker implementation found in `services/tracker.js`.  If you want to generate the torrents again then run:
 
-```
+```shell
-sh scripts/mktorrents.sh sample.mp4
+mktorrent -v -w http://127.0.0.1:5001/images/sample_video.mp4 \
+  -a ws://127.0.0.1:9001/ \
+  -o static/images/sample_video.mp4.torrent \
+  -p -l 18 static/images/sample_video.mp4
+cp -r static/images public/images
 ```
 
-It uses the [mktorrents](https://github.com/pobrn/mktorrent) to generate the torrent since it is faster.  Be careful of the WebTorrent specific options I use in the ``services/mktorrents.sh`` that are needed for WebTorrent to understand the torrent:
+It uses the [mktorrent](https://github.com/pobrn/mktorrent) to generate the torrent since it is faster.  Be careful of the WebTorrent specific options I use in the `mktorrent` that are needed for WebTorrent to understand the torrent:
 
 * `-p` -- Sets the private flag.  This isn't needed for WebTorrent but is
   needed if you want to add extra protections to people accessing your content
   only after they log in.
-* `-l 15` -- Sets the piece length to 15.
+* `-l 18` -- Sets the piece length to 18, which is what WebTorrent seems to need.
 * `-w 127.0.0.1` -- Sets an initial web URL to use as a source.  You
   should remove this if you want them to only go through the tracker and other
   users.
+* `-a ws://127.0.0.1:9001/` -- Tells WebTorrent where the tracker is located.

+# Bugs

+1. It looks like WebTorrent has a problem getting the last chunk in some situations and I'm quite sure why.  If you have an idea let me know.
 
-Download Link
+# Download Link
-===
 
-If you want to let people download the video then add the `download={ true }` property.  This demo sets that option so you can see how it works.
