+## @electron-forge/plugin-integrity-digest
+
+This plugin provides a `packageAfterCopy` hook for calculating and storing integrity digests when packaging with Electron Forge.
+
+### Usage
+
+Install `@electron-forge/plugin-integrity-digest` and add this plugin to the `plugins` array in your Forge configuration:
+
+```shell
+# Yarn
+yarn add --dev @electron-forge/plugin-integrity-digest
+
+# npm
+npm i -D @electron-forge/plugin-integrity-digest
+```
+
+```js
+// forge.config.js
+
+const { IntegrityDigestPlugin } = require('@electron-forge/plugin-integrity-digest');
+
+const forgeConfig = {
+  plugins: [new IntegrityDigestPlugin()],
+};
+
+module.exports = forgeConfig;
+```
+
+If desired, you can pass a specific version of integrity digest to calculate and store. Currently, the only version is `1`.
+
+```js
+const forgeConfig = {
+  plugins: [new IntegrityDigestPlugin({version: 1})],
+};
+```
