-Delete the oldest 3 version of a package hosted in a different repo than the one executing the workflow
+  __Example__
 
-```yaml
-- uses: actions/delete-package-versions@v1
-  with:
-    owner: 'github'
-    repo: 'packages'
-    package-name: 'test-package'
-    num-old-versions-to-delete: 3
-    token: ${{ secrets.GITHUB_PAT }}
-```
+  Delete the oldest 3 version of a package hosted in the same repo as the workflow
+
+  ```yaml
+  - uses: actions/delete-package-versions@v2
+    with:
+      package-name: 'test-package'
+      num-old-versions-to-delete: 3
+  ```
+
+  To delete the oldest x number of versions of a package hosted in a different repo than the workflow the __owner__, __repo__, __package-name__, __token__ and __num-old-versions-to-delete__ inputs are required.
+
+  The [token][token] needs the delete packages and read packages scope. It is recommended [to store the token as a secret][secret]. In this example the [token][token] was stored as a secret named __GITHUB_PAT__.
+
+  __Example__
+
+  Delete the oldest 3 version of a package hosted in a different repo than the one executing the workflow

+  ### Delete oldest version of a package
+
+  To delete the oldest version of a package that is hosted in the same repo as the workflow the __package-name__ input is required.
+
+  __Example__
+
+  ```yaml
+  - uses: actions/delete-package-versions@v2
+    with:
+      package-name: 'test-package'
+  ```

+  ```
+
+  <br>
+
+  ### Delete a specific version of a package
+
+  To delete a specific version of a package that is hosted in the same repo as the workflow the __package-version-ids__ input is required.
+
+  Package version ids can be retrieved via the [GitHub GraphQL API][api]
+
+  __Example__
+
+  ```yaml
+  - uses: actions/delete-package-versions@v2
+    with:
+      package-version-ids: 'MDE0OlBhY2thZ2VWZXJzaW9uOTcyMDY3'
+  ```
+
+  To delete a specific version of a package that is hosted in a different repo than the workflow the __package-version-ids__ and __token__ inputs are required.

+  ```
+
+  <br>
+
+  ### Delete multiple specific versions of a package
+
+  To delete multiple specifc versions of a package that is hosted in the same repo as the workflow the __package-version-ids__ input is required.
+
+  The __package-version-ids__ input should be a comma separated string of package version ids. Package version ids can be retrieved via the [GitHub GraphQL API][api].
+
+  __Example__
+
+  ```yaml
+  - uses: actions/delete-package-versions@v2
+    with:
+      package-version-ids: 'MDE0OlBhY2thZ2VWZXJzaW9uOTcyMDY3, MDE0OlBhY2thZ2VWZXJzaW9uOTcyMzQ5, MDE0OlBhY2thZ2VWZXJzaW9uOTcyMzUw'
+  ```
+
+  To delete multiple specifc versions of a package that is hosted in a repo other than the workflow the __package-version-ids__, __token__ inputs are required.
+
+  The __package-version-ids__ input should be a comma separated string of package version ids. Package version ids can be retrieved via the [GitHub GraphQL API][api].
+
+  The [token][token] needs the delete packages and read packages scope. It is recommended [to store the token as a secret][secret]. In this example the [token][token] was stored as a secret named __GITHUB_PAT__.
