I posted my flexget configuration a couple of years back (here) and thought it was about time I repost my configuration. This new file is compatible with the latest version of flexget 1.0r2995 as of this post.

In ~/.flexget/config.yml:

Make sure to customize this configuration to work with your setup! I also have the following in my crontab set to run hourly:

@hourly /usr/local/bin/flexget -v --cron > /home/<username>/log/flexget.log

Make sure to replace <username> with your own user name!
