+// By using this approach, it is now our own responsibility to keep monaco-editor and @monaco-editor/react compatible.
+// @monaco-editor/react uses @monaco-editor/loader, and @monaco-editor/loader uses a specific version of monaco-editor.
+// So when you need to update them, you do
+// 1. Pick a version of @monaco-editor/react.
+// 2. Inspect @monaco-editor/loader in package-lock.json to see the actual version of @monaco-editor/loader
+// 3. Inspect https://github.com/suren-atoyan/monaco-loader/blob/master/src/config/index.js to see what version of monaco-editor it is using.
+// 4. Install the same version of monaco-editor.
+//
+// Note that monaco-editor has some breaking changes in 0.45.0
+// See https://github.com/microsoft/monaco-editor/blob/main/CHANGELOG.md#0450
+// So the highest version we can use is 0.44.0, until @monaco-editor/react supports >= 0.45.0
