This takes the YAML formatted meetings.yaml file and converts to a .ics file that can be used as input into a calendar. This process allows for adding additional meetings in the future, just by adding another record to the yaml file, as well as automating ical generation and email. The tool that is used to do the conversion is yaml2ical. Follow the usage and installation instructions here:
https://github.com/openstack-infra/yaml2ical
Start by editing meetings.yaml, changing the fields to the needed values. You can get more description on the supported fields at the link above.
Once you are happy with the info in the yaml file, run the tool yaml2ical:
$ yaml2ical -f -y . -o meetings.ics
The -f parameter forces an overwrite of the existing ical file.
