What issue do you have?

after install event calendar with these instructions...
https://joplinapp.org/plugins/downloadPlugin.html?plugin=com.wemakemachines.joplin.plugin.event-calendar

after restart joplin, i can't find event calendar.

is it broken?

Does not appear to be. It seems that you need to create your event calendar using code like this in a note:

```joplin-plugin-event-calendar
group: day
events:
- date: 2012-11-05
  icon: 🔥
  title: Bonfire night
  text: We have been collecting wood for a week now...
  bgColor: orange
```

The plugin site you linked to above also contains the instructions on how to use the plugin.
