+### Delete an Artifact
+
+To delete an artifact, all you need is the name.
+
+```js
+const {id} = await artifact.deleteArtifact(
+  // name of the artifact
+  'my-artifact'
+)
+
+console.log(`Deleted Artifact ID '${id}'`)
+```
+
+It also supports options to delete from other repos/runs given a github token with `actions:write` permissions on the target repository is supplied.
+
+```js
+const findBy = {
+  // must have actions:write permission on target repository
+  token: process.env['GITHUB_TOKEN'],
+  workflowRunId: 123,
+  repositoryOwner: 'actions',
+  repositoryName: 'toolkit'
+}
+
+
+const {id} = await artifact.deleteArtifact(
+  // name of the artifact
+  'my-artifact',
+  // options to find by other repo/owner
+  { findBy }
+)
+
+console.log(`Deleted Artifact ID '${id}' from ${findBy.repositoryOwner}/ ${findBy.repositoryName}`)
+```
+
 ### Downloading from other workflow runs or repos
 
 It may be useful to download Artifacts from other workflow runs, or even other repositories. By default, the permissions are scoped so they can only download Artifacts within the current workflow run. To elevate permissions for this scenario, you must specify `options.findBy` to `downloadArtifact`.
