 - `source`: optional, defaults to `master.m3u8`.
 - `title`: optional, allows overriding the browser tab title.
 
-Here are commands you can use to encode and upload a video to IPFS:
+Here is a script you can use to encode a video into a HLS folder with a playlist:
 
 ```
-mkdir output
-cd output
-ffmpeg -i ../yourVideoFilename.mp4 -profile:v baseline -level 3.0 -start_number 0 -hls_time 5 -hls_list_size 0 -f hls master.m3u8
-ipfs add -Qr .

+(If you add that to your path as `recode-to-hls` you can convert a folder of MP4 files with the command `ls *.mp4 -1 | xargs -d "\n" recode-to-hls`.)

+A folder produced this way can be posted to IPFS, and that hash is used in this page URL. Here are two hashes created following this format:
+
+`QmdpAidwAsBGptFB3b6A9Pyi5coEbgjHrL3K2Qrsutmj9K` - Big Buck Bunny
+`QmYzdc44xBkVgp8aWJW57KprjDs5j2hmN8g7eDqm5pvY8L` - Royal Path episode 001
+
 The output from the `ipfs` command is the hash to use with this page.
