-# Example: Import Map
+# Example: Lodash from jsDelivr
 
-You can use import maps to map imports with `importMap` option:
-
-```javascript
-esbuildCachePlugin({
-  importMap: {
-    "imports": {
-      "https://example.com/foo/": "./src/polyfill/foo/"
-    },
-    "scopes": {
-      "./src/foo.ts": {
-        "https://example.com/foo/": "./src/polyfill/bar/"
-      }
-    }
-  },
-}),
-```
+Using Lodash from jsDelivr, mapping `lodash` to remote URL (see `import_map.json`.)
