While there's transmission-rss available, it didn't suit my use case, hence the reason to create this little piece of code to start downloads with Transmission from an RSS source provided by Jackett.
You need to set the necessary parameters in a config.yml file, you can use config.example.yml as an example to configure the Jackett Feeds and your Transmission instance.
After that, you can setup cron jobs to start processing the feeds.
