# Standalone skills scenario

> Continued development of a Classification or Document skill in Vantage, without collecting documents from an in-production skill.

This scenario describes how to continue developing a Classification or Document skill in Vantage. It does not cover collecting documents from a skill already running in production.

## Release a skill to production

To make a skill available for processing documents:

<Steps>
  <Step title="Create the skill">
    Create the skill in Vantage or [Advanced Designer](/vantage/documentation/advanced-designer/introduction).
  </Step>

  <Step title="Configure and train">
    Configure and train the skill. For details, see [Classification skill](/vantage/documentation/skill-designer/classification/classification-skill), [Document skill](/vantage/documentation/skill-designer/document/document-skill), or the [Advanced Designer guide](/vantage/documentation/advanced-designer/introduction).
  </Step>

  <Step title="Publish">
    Publish the skill when you're ready to expose it to users — for production or testing. Publishing assigns a version number and makes the skill available for document processing via API or connectors.
  </Step>
</Steps>

<Note>
  If a skill has no version number in the **Skill Catalog**, it hasn't been published yet and is not yet available for document processing.
</Note>

## Edit a skill that is available in production

To adjust a published skill:

<Steps>
  <Step title="Open the published skill">
    Open the skill. Vantage creates a new draft version; the published version stays live, so editing does not affect other users.
  </Step>

  <Step title="Make changes and publish">
    Make your changes and publish. Vantage creates a new published version with an incremented version number. Users who consume the skill via API or connectors always receive the latest published version, so the change applies automatically.
  </Step>
</Steps>

For more information, see [Edit a skill](/vantage/documentation/skill-catalog/edit-skill).

## Roll a skill back to a previous version

If you aren't satisfied with a new skill version, delete it and roll back to the previous one:

<Steps>
  <Step title="Open the skill">
    Open **Skill Catalog** and click the skill version number.
  </Step>

  <Step title="Duplicate to preserve the version">
    To keep a copy of the version you're about to delete, click the **Duplicate skill** icon to copy it to a new skill.
  </Step>

  <Step title="Delete the latest version">
    Click the **Delete** icon next to the latest version. Users are switched to the second-most-recent version in the list.

    <Warning>
      Deleting a version is permanent.
    </Warning>
  </Step>
</Steps>

<Note>
  A duplicated version becomes a separate skill. You can continue developing it independently, but it can't be merged back into the original skill later. To use the new skill, users must update the skill ID in their API calls or connector settings.
</Note>
