You can use HTML tables to show the diff quite nicely, see:

Code:

- New feature: **Support multiple input parameters on Implementation**
  <table>
  <tr>
  <td> Before </td> <td> After </td>
  </tr>
  <tr>
  <td>

  ```yaml
  inject:
    additionalInput:
      additional-parameters:
          replicaCount: 3
  ```

  </td>
  <td>

  ```yaml
  inject:
    additionalParameters:
      - name: rds-parameters
        value:
          replicaCount: 3
  ```

  </td>
  </tr>
  </table>
