+## What's New
+
+* Added support for multiple paths, [glob patterns](https://github.com/actions/toolkit/tree/master/packages/glob), and single file caches. 
+
+```yaml
+- name: Cache multiple paths
+  uses: actions/cache@v2
+  with:
+    path: |
+      ~/cache
+      !~/cache/exclude
+      **/node_modules
+    key: ${{ runner.os }}-${{ hashFiles('**/lockfiles') }}
+```
+
+* Increased performance and improved cache sizes using `zstd` compression for Linux and macOS runners
+* Allowed caching for all events with a ref. See [events that trigger workflow](https://help.github.com/en/actions/reference/events-that-trigger-workflows) for info on which events do not have a `GITHUB_REF`
+* Released the [`@actions/cache`](https://github.com/actions/toolkit/tree/master/packages/cache) npm package to allow other actions to utilize caching
+* Added a best-effort cleanup step to delete the archive after extraction to reduce storage space
+
+Refer [here](https://github.com/actions/cache/blob/v1/README.md) for previous versions

 ## Usage
 
 ### Pre-requisites
 Create a workflow `.yml` file in your repositories `.github/workflows` directory. An [example workflow](#example-workflow) is available below. For more information, reference the GitHub Help Documentation for [Creating a workflow file](https://help.github.com/en/articles/configuring-a-workflow#creating-a-workflow-file).
 
 ### Inputs
 
-* `path` - A directory to store and save the cache
+* `path` - A list of files, directories, and wildcard patterns to cache and restore. See [`@actions/glob`](https://github.com/actions/toolkit/tree/master/packages/glob) for supported patterns. 
 * `key` - An explicit key for restoring and saving the cache
 * `restore-keys` - An ordered list of keys to use for restoring the cache if no cache hit occurred for key
