+description: Enable automatic installation for your content package if data with a matching dataset is ingested in Elasticsearch.

+# Enable automatic installation for content packages [auto-install-content-packages]
+
+As of version 9.2.0, {{kib}} can automatically install content packages when it detects matching data in {{es}}. This feature uses the `data_stream.dataset` attribute to identify relevant content and install assets such as dashboards and alerts without requiring user intervention.
+
+When data is ingested with a specific `data_stream.dataset` value, {{kib}} checks the {{package-registry}} for content packages that have at least one matching dataset defined in their `discovery.datasets` field. If there is a matching content package, {{kib}} automatically installs it.
+
+## Requirements [auto-install-content-packages-requirements]
+
+- {{kib}} version 9.2.0 or later
+- The `format_version` in the content package's `manifest.yml` must specify `3.4.1` or later.
+
+## Configuration [auto-install-content-packages-configuration]
+
+To enable automatic installation for your content package, add the `discovery.datasets` property to your package's `manifest.yml` file. This property should be defined as an array of objects, each with a `name` field specifying a dataset. For example:
+
+```yml
+# my_content_package/manifest.yml
+
+format_version: 3.4.1
+name: my_content_package
+version: 1.0.0
+type: content
+
+# ...
+
+discovery:
+  fields: []
+  datasets:
+    - name: my.dataset
+    - name: other.dataset
+```
+
+If you publish a content package with this configuration, {{kib}} will automatically install the package when data with `data_stream.dataset: "my.dataset"` or `data_stream.dataset: "other.dataset"` is ingested in {{es}}.
