+Description:
+CodeMirror is a code editor for the browser.
+
+To update this package, adjust the version ranges in package.json if necessary, and run the following command:
+
+```bash
+./rebuild.sh
+```
+
+It will use npm to locally install the necessary packages and their dependencies, and bundle them into a single file (codemirror.js and codemirror.d.ts) with rollup.
