+# What's new
+
+- Download all artifacts at once
+- Port entire action to typescript from a runner plugin so it is easier to collaborate and accept contributions
+
+Refer [here](https://github.com/actions/download-artifact/tree/v1) for the previous version

+# Download All Artifacts
+
+If the `name` input parameter is not provided, all artifacts will be downloaded. To differentiate between downloaded artifacts, a directory denoted by the artifacts name will be created for each individual artifact.
+
+Example, if there are two artifacts `Artifact-A` and `Artifact-B`, and the directory is `etc/usr/artifacts/`, the directory structure will look like this:
+```
+  etc/usr/artifacts/
+      Artifact-A/
+          ... contents of Artifact-A
+      Artifact-B/
+          ... contents of Artifact-B
+```
+
+Download all artifacts to a specific directory

+# @actions/artifact package

+Internally the [@actions/artifact](https://github.com/actions/toolkit/tree/master/packages/artifact) NPM package is used to interact with artifacts. You can find additional documentation there along with all the source code related to artifact download.
