# Annotations

[Annotations](https://kubernetes.io/docs/concepts/overview/working-with-objects/annotations/)
let you attach custom metadata to Telemetry Pipeline resources. These annotations won't
affect Telemetry Pipeline's behavior.

  <Tab title="Pipeline CLI" id="annotations-cli">
    [Pipeline CLI](/ingest/pipeline/pipeline-cli) lets you specify tolerations for new resources.
    However, you can't use Pipeline CLI to add or modify tolerations for an existing
    resource.

    When you create a new resource, add the `--annotations` flag to your operation,
    and include an annotations string.

    The string that specifies your annotations must follow this syntax:

    ```text theme={null}
    annotation1=value1,annotation2=value2
    ```
  </Tab>

  <Tab title="Helm" id="annotations-helm">
    Helm lets you add annotations to new resources, and add or modify annotations
    for existing resources.

    To do so, add the following key/value pair to your Helm chart:

    ```yaml theme={null}
    calyptiaAnnotations: STRING
    ```

    Replace *`STRING`* with the string that specifies your annotations.

    The string that specifies your annotations must follow this syntax:

    ```text theme={null}
    annotation1=value1,annotation2=value2
    ```

    However, if you're using Helm through the command line, you must escape any
    commas with a backslash (`\`) to prevent Helm from incorrectly splitting the
    string into multiple values. For example,
    `--set calyptiaAnnotations='annotation1=value1\,annotation2=value2'` is valid syntax.
