+## Collector tags
+
+With remote management, you can tag your [OpenTelemetry Collectors](/docs/send-data/opentelemetry-collector) to categorize and group them. These tags are also enriched in your data, enabling you to use them in your dashboards and searches.
+
+:::note
+- Collector tags will only be editable for collectors with version `0.114.0` and above.
+- For default collector tags, you can only edit the **Values**.
+- System collector tags like `sumo.disco.enabled` cannot be added, updated, or deleted.
+:::
+
+You can add collector tags during OTEL collector setup as described in the previous section. Follow the below steps to add, update, or delete the collector tags after creation:
+
+1. Navigate to the **OpenTelemetry Collection** page.<br/><img src={useBaseUrl('img/send-data/opentelemetry-collection.png')} alt="opentelemetry-collection" style={{border:'1px solid gray'}} width="700"/>
+1. Click on the desired collector where you need to add collector tags.
+1. In the right pane, scroll to the **Collector Tags** section and click **Edit**.<br/><img src={useBaseUrl('img/send-data/collector-tags-edit.png')} alt="collector-tags-edit" style={{border:'1px solid gray'}} width="500"/>
+1. In the edit window, click **+ Add tags** to add a new tag. You can also update or delete the required tags. Then click **Proceed**.<br/><img src={useBaseUrl('img/send-data/add-delete-update-tags.png')} alt="add-delete-update-tags" style={{border:'1px solid gray'}} width="500"/>

+1. You will be redirected to the **Mapped Source Template** section, which displays the mapped source templates for the collector tags added. This window also displays the **Compatible** and **Incompatible Version** details for the mapped source template for the collector.<br/><img src={useBaseUrl('img/send-data/mapped-source-templates.png')} alt="mapped-source-templates" style={{border:'1px solid gray'}} width="500"/>
+1. If there are any incompatible source templates, [upgrade the source template](/docs/send-data/opentelemetry-collector/remote-management/source-templates/manage-source-templates/#upgrade-a-source-template) to ensure compatibility.
+1. Once the source template is upgraded and is compatible, enter **PROCEED** and click **Confirm**.<br/><img src={useBaseUrl('img/send-data/confirm-the-tags.png')} alt="confirm-the-tags" style={{border:'1px solid gray'}} width="500"/>
