+Exposes an iCal feed as JSON for querying with the JSON API plugin.
+
+Examples:
+  - input: ./fixtures/calendar.ics
+  - output: ./fixtures/calendar.json
+
+Url to query: <hostname:port>/annotations - does not do any filtering or querying (exposes all events). The JSON result can be queried as a metric to display in tables, or as annotations.
+
+You can get extra information from the JSON using the JSONata features of the JSON API plugin. Examples:
+
+- `duration`: `$.(timeEnd-time)`
+- `timeSinceEvent`: `$.(timeEnd-$millis())`
+
+You can use values in transforms to filter data out of tables.
