# Document skill settings in Advanced Designer

> Configure a Document skill's General, OCR, Fields, Rules, and Parameters tabs in Advanced Designer — including Technology Core and derived skills.

To open a Document skill's settings, click the settings button next to the skill name. The dialog has five tabs.

## General

* Skill name and description.
* [Technology Core](/vantage/documentation/advanced-designer/upgrading-to-new-version) version.
* Base skill name and version (for [derived skills](/vantage/documentation/advanced-designer/document-skills/derived)).

## OCR Languages

* **Recognition languages** — the default set is English, French, German, and Spanish. Languages enabled here apply only to documents uploaded after the change.
* **Handwritten text recognition** — enabled by default. Available for the languages listed in the product specifications. For skills built on FlexiLayouts, the option is also limited to the languages declared when the FlexiLayout was created, and one of those languages must be active in the recognition list.

<Note>
  In a derived skill, you cannot add new recognition languages or enable handwritten text recognition if either is disabled on the base skill. See [Configure text recognition](/vantage/documentation/advanced-designer/document-skills/derived-configure#configure-text-recognition).
</Note>

## Fields

A list of every field used in the skill, including inherited and custom fields. The hierarchy mirrors the data form. Use this tab to confirm which fields the skill exposes before configuring extraction.

## Rules

A list of every rule used in the skill, including inherited and custom rules. Use this tab to review the validation logic that runs against extracted values.

## Parameters

Skill parameters expose tuning knobs that adjust skill behavior without retraining — see [Configure Document skill parameters](/vantage/documentation/advanced-designer/document-skills/skill-params).
