+
+<ComponentMapperBar prefix="ant" href="https://ant.design/" />
+
+Ant Design provides components from [Ant Design Design System](https://ant.design/).
+
+## Installation
+
+```bash
+npm install --save @data-driven-forms/ant-component-mapper
+```
+or
+```bash
+yarn add @data-driven-forms/ant-component-mapper
+```
+
+Ant Design has to be installed seperately. Please follow their [guidelines](https://ant.design/docs/react/introduce#Installation).
+
+## ValidateOnMount
+
+Ant Design provides an option to validate a field when the component is mounted. Just set `validateOnMount` to `true`.
+
+```jsx
+{
+    component: 'text-field',
+    name: 'required-field',
+    validate: [{type: 'required'}],
+    validateOnMount: true
+}
+```
+
+This field will show the error immediately.
+
+## Layout Specification
+
+Ant Design provides horizontal and vertical layouts for form. Layout can be specified by passing a `layout` prop to `formTemplate`. By default it is set to `vertical`.
+
