+ * Alternatively, import toolkit modules you use to minify the plugin size.
+ *
+ * Steps to replace the default `ztoolkit: ZoteroToolkit` with your `ztoolkit: MyToolkit`:
+ *
+ * 1. Uncomment this file's line 30:            `ztoolkit: new MyToolkit(),`
+ *    and comment line 31:                      `ztoolkit: new ZoteroToolkit(),`.
+ * 2. Uncomment this file's line 10:            `ztoolkit: MyToolkit;` in this file
+ *    and comment line 11:                      `ztoolkit: ZoteroToolkit;`.
+ * 3. Uncomment `./typing/global.d.ts` line 12: `declare const ztoolkit: import("../src/addon").MyToolkit;`
+ *    and comment line 13:                      `declare const ztoolkit: import("zotero-plugin-toolkit").ZoteroToolkit;`.
+ *
+ * You can now add the modules under the `MyToolkit` class.
