+# microsoft-calendar
+
+Welcome to the microsoft-calendar plugin!
+
+_This plugin was created through the Backstage CLI_
+
+You can use this plugin by import MicrosoftCalendar from "@internal/plugin-microsoft-calendar"
+
+> import { MicrosoftCalendar } from "@internal/plugin-microsoft-calendar"
+
+![MicrosoftCalendar plugin screenshot](./docs/microsoft-calendar-plugin.png)
+
+You can also serve the plugin in isolation by running `yarn start` in the plugin directory.
+This method of serving the plugin provides quicker iteration speed and a faster startup and hot reloads.
+It is only meant for local development, and the setup for it can be found inside the [/dev](./dev) directory.
