 ### Additional entitlements
 
+Every app running under the App Sandbox will run under a limited set of permissions,
+which limits potential damage from malicious code.
 Depending on which Electron APIs your app uses, you may need to add additional
 entitlements to your app's entitlements file. Otherwise, the App Sandbox may
 prevent you from using them.
 
+Entitlements are specified using a file with format like
+property list (`.plist`) or XML. You must provide an entitlement file for the
+application bundle itself and a child entitlement file which basically describes
+an inheritance of properties, specified for all other enclosing executable files
+like binaries, frameworks (`.framework`), and dynamically linked libraries (`.dylib`).
+
+A full list of entitlements is available in the [App Sandbox][app-sandboxing]
+documentation, but below are a few entitlements you might need for your
+MAS app.
+
+With `@electron/osx-sign`, you can set custom entitlements per file as such:
+
+```js @ts-nocheck
+const { signAsync } = require('@electron/osx-sign')
+
+function getEntitlementsForFile (filePath) {
+  if (filePath.startsWith('my-path-1')) {
+    return './my-path-1.plist'
+  } else {
+    return './alternate.plist'
+  }
+}
+
+signAsync({
+  optionsForFile: (filePath) => ({
+    // Ensure you return the right entitlements path here based on the file being signed.
+    entitlements: getEntitlementsForFile(filePath)
+  })
+})
+```
