+name: Add a trusted dependency
+---
+
+Unlike other npm clients, Bun does not execute arbitrary lifecycle scripts for installed dependencies, such as `postinstall` and `node-gyp` builds. These scripts represent a potential security risk, as they can execute arbitrary code on your machine.
+
+---
+
+To tell Bun to allow lifecycle scripts for a particular package, add the package to `trustedDependencies` in your package.json.
+
+```json-diff
+  {
+    "name": "my-app",
+    "version": "1.0.0",
++   "trustedDependencies": ["my-trusted-package"]
+  }
+```
+
+<!-- Bun maintains an allow-list of popular packages containing `postinstall` scripts that are known to be safe. To run lifecycle scripts for packages that aren't on this list, add the package to `trustedDependencies` in your package.json. -->
+
+---
+
+Note that this only allows lifecycle scripts for the specific package listed in `trustedDependencies`, _not_ the dependencies of that dependency!
+
+Soon, Bun will include a built-in allow-list that automatically allows lifecycle scripts to be run by popular packages that are known to be safe. This is still under development.
+

+
+See [Docs > Package manager > Trusted dependencies](/docs/cli/install#trusted-dependencies) for complete documentation of trusted dependencies.
