+Use this  plugin for publishing files and artifacts to GitHub releases. You
+can override the default configuration with the following parameters:
+
+* `api_key` - GitHub oauth token with public_repo or repo permission
+* `files` - Files to upload to GitHub Release; globs are allowed
+* `base_url` - GitHub base URL; only required for GHE
+* `upload_url` - GitHub upload URL; only required for GHE
+
+Sample configuration:
+
+```yaml
+publish:
+  github_release:
+    api_key: my_github_api_key
+    files:
+      - dist/*
