 Store this file as channel.yml in the same directory where the mp3 files of your podcast reside. The channel definition is expected to be present in the same directory as your mp3 files, but this can be overridden using a command line switch. You can find a [more elaborate example](http://github.com/nerab/dropcaster/blob/master/doc/sample-channel.yml) for the channel definition in the doc folder of the Dropcaster gem. You can find it by running `gem open dropcaster`.

 Besides generating an RSS feed, dropcaster can also generate HTML that can be used as a home page for your podcast. The template directory contains a sample template that can be used to get started:
 
-        $ dropcaster --channel-template templates/channel.html.erb
+    $ dropcaster --channel-template templates/channel.html.erb
 
 As discussed above, the output of this command can be written to a file, too:
 
-        $ dropcaster --channel-template templates/channel.html.erb > ~/Dropbox/Public/allabouteverything.html
+    $ dropcaster --channel-template templates/channel.html.erb > ~/Dropbox/Public/allabouteverything.html
 
 Dropcaster works exactly the same, whether it generates an RSS feed or a HTML page. Therefore, all options discussed before also apply when generating HTML.
