# Links in Pull Requests view

The pull request view in GitHub is probably the most important place for developers. Tentacle makes sure that the links defined in the `catalog-info.yaml` file are also visible in the pull request view. For this to work, you need to add the `pullRequestLinks` attribute to the `catalog-info.yaml` file.

<CodeGroup>
  ```diff catalog-info.yaml theme={null}
  apiVersion: backstage.io/v1alpha1
  kind: Component
  metadata:
    name: artist-service
    links:
      - url: https://admin.example.com
        title: Admin Dashboard
  + tentacle:
  +   pullRequestLinks:
  +    - url: https://dev.example.com
  +      title: Dev instance
  spec:
    type: service
    lifecycle: production
    owner: team-awesome
  ```

  ```yaml raw theme={null}
  apiVersion: backstage.io/v1alpha1
  kind: Component
  metadata:
    name: artist-service
    links:
      - url: https://admin.example.com
        title: Admin Dashboard
    tentacle:
      pullRequestLinks:
       - url: https://dev.example.com
         title: Dev instance
  spec:
    type: service
    lifecycle: production
    owner: team-awesome
  ```
</CodeGroup>

But that's not all! Tentacle also provides a way to define dynamic links that will take your developers to the right place in the right context. For example, you can define a link that will take your developers to the pull request view of the current repository.

<CodeGroup>
  ```diff catalog-info.yaml theme={null}
  apiVersion: backstage.io/v1alpha1
  kind: Component
  metadata:
    name: artist-service
    links:
      - url: https://admin.example.com
        title: Admin Dashboard
    tentacle:
      pullRequestLinks:
        - url: https://dev.example.com
          title: Dev instance
  +     - title: Preview
  +       url: https://preview-{% $pullrequest.number %}.dev.example.com
  +     - title: JIRA {% $pullrequest.jira_prefix %}
  +       url: https://jira.company.com/{% $pullrequest.jira_prefix %}
  spec:
    type: service
    lifecycle: production
    owner: team-awesome
  ```

  ```yaml raw theme={null}
  apiVersion: backstage.io/v1alpha1
  kind: Component
  metadata:
    name: artist-service
    links:
      - url: https://admin.example.com
        title: Admin Dashboard
    tentacle:
      pullRequestLinks:
        - url: https://dev.example.com
          title: Dev instance
        - title: Preview
          url: https://preview-{% $pullrequest.number %}.dev.example.com
        - title: JIRA {% $pullrequest.jira_prefix %}
          url: https://jira.company.com/{% $pullrequest.jira_prefix %}
  spec:
    type: service
    lifecycle: production
    owner: team-awesome
