+## Caveat: Online dependency
+
+Due to the complicated nature of bundling the Monaco Editor, the plugin currently relies on
+a hosted version of the editor. This means that the plugin needs an internet connection to
+work, and has a dependency on the hosted editor, which is currently available on
+https://embeddable-monaco.lukasbach.com.
+
+I hope to remove this dependency in the future, but this was the easiest way to get the
+plugin to work for now.
