 ### 4) Build forge.mjs (ES module)
 
-Install rollup and create a rollup configuration:
+Since `node-forge` uses webpack and has Node.js built-ins that can be tricky to bundle with rollup for the browser, the most stable way to generate the ES module is to convert the already-built `forge.js`.
 
-```bash
-npm install --save-dev rollup @rollup/plugin-node-resolve @rollup/plugin-commonjs
-```
-
-Create `rollup.config.js`:
+Create a script `convert-forge-to-mjs.js`:
 
 ```javascript
-import resolve from '@rollup/plugin-node-resolve';
-import commonjs from '@rollup/plugin-commonjs';
-
-export default {
-  input: 'lib/index.js',
-  output: {
-    file: 'dist/forge.mjs',
-    format: 'es',
-    sourcemap: true
-  },
-  plugins: [
-    resolve(),
-    commonjs()
-  ]

-Build the ES module:
+Run the script:
 
 ```bash
-npx rollup -c rollup.config.js
+node convert-forge-to-mjs.js
