I am grateful to have crossed paths with the 5545 spec. However, I found that available resources on https://icalendar.org/ & from google are either moderately dense or lacking.
I was hoping to find an iCalendar tutorial, iCalendar 101, Brief intro to iCalendar, RFC 5545 Crash Course or similarly suited resource.
What introductory resources are out there explaining how to use/implement rfc 5545? Also, is there a suitable competing spec?
I know that some people find these questions obnoxious, so I will confirm that "yes", I did search for a wide set of combinations of the term "introduction, icalendar, rfc, 5545, tutorial" etc before asking this community :)
