# A reusable podcast RSS feed generated from the channel information in _data/channel.yml and the episodes in _episodes/*.md which works on Apple Podcasts
# Format specification: https://podcasters.apple.com/support/823-podcast-requirements

# I want to improve this by make only parsing the optional tags if they are set (not possible with Jekyll / Liquid)
