+#### Keep output directory after packaging
+
+You can keep the output directory (defaults to `.webpack`) from being removed
+after build.
+
+Just add `keepOutputDirectory: true`
+
+```yaml
+# serverless.yml
+custom:
+  webpack:
+    keepOutputDirectory: true

+This can be useful, in case you want to upload the source maps to your Error

 #### Examples
 
 You can find an example setups in the [`examples`][link-examples] folder.
