+## Description
+
+The Wazuh Indexer team is responsible for the maintenance of the third-party integrations hosted in the wazuh/wazuh-indexer repository. We must ensure these integrations work under new releases of the third-party software (Splunk, Elastic, Logstash, …) and our own.
+
+For that, we need to:
+
+-   [ ] Create a pull request that upgrades the components to the latest version.
+-   [ ] Update our testing environments to verify the integrations work under new versions.
+-   [ ] Test the integrations, checking that:
+  - The Docker Compose project starts without errors.
+  - The data arrives to the destination.
+  - All the dashboards can be imported successfully.
+  - All the dashboards are populated with data.
+-   [ ] Finally, upgrade the compatibility matrix in integrations/README.md with the new versions.
+
+> [!NOTE]
+> * For Logstash, we use the logstash-oss image.
+> * For Wazuh Indexer and Wazuh Dashboard, we use the opensearch and opensearch-dashboards images. These must match the opensearch version that we support (e.g: for Wazuh 4.9.0 it is OpenSearch 2.13.0).
