 - `allowedStrings` - An array of unique string values that would otherwise warn, but will be ignored.
 - `ignoreProps` (default: `false`) - When `true` the rule ignores literals used in props, wrapped or unwrapped.
 - `noAttributeStrings` (default: `false`) - Enforces no string literals used in attributes when set to `true`.

+
+### `elementOverrides`
+
+The `elementOverrides` option allows you to specify different options for
+different elements. This is useful when you want to enforce different rules for
+different elements. For example, you may want to allow string literals in
+`Button` elements, but not in the rest of your application.
+
+The element name only accepts component names. HTML element tag names are not supported.
+Component names are case-sensitive and should exactly match the name of
+the component as it is used in the JSX. It can also be the name of a compound
+component (ie. `Modal.Button`).
+
+Specifying options creates a new context for the rule, so the rule will only
+apply the new options to the specified element and its children (if
+`applyToNestedElements` is `true` - see below). This means that the root rule options will
+not apply to the specified element.
+
+In addition to the options above (`noStrings`, `allowedStrings`,
+`noAttributeStrings` and `ignoreProps`), you can also specify the the following options
+that are specific to `elementOverrides`:
+
+- `allowElement` (default: `false`) - When `true` the rule will allow the
+  specified element to have string literals as children, wrapped or unwrapped
+  without warning.
+- `applyToNestedElements` (default: `true`) - When `false` the rule will not
+  apply the current options set to nested elements. This is useful when you want
+  to apply the rule to a specific element, but not to its children.
+
+**Note**: As this rule has no way of differentiating
+between different componets with the same name, it is recommended to use this
+option with specific components that are unique to your application.
+
+#### `elementOverrides` Examples
+
+The following are **correct** examples that demonstrate how to use the `elementOverrides` option:
+
+```js
+// "react/jsx-no-literals": [<enabled>, {"elementOverrides": { "Button": {"allowElement": true} }}]
+
+var Hello = <div>{'test'}</div>;
+var World = <Button>test</Button>;
+```
+
+```js
+// "react/jsx-no-literals": [<enabled>, {"elementOverrides": { "Text": {"allowElement": true} }}]
+
+var World = <Text>Hello <a href="a">world</a></Text>;
+```
+
+```js
+// "react/jsx-no-literals": [<enabled>, {"elementOverrides": { "Text": {"allowElement": true, "applyToNestedElements": false} }}]
+
+var linkText = 'world';
+var World = <Text>Hello <a href="a">{linkText}</a></Text>;
+```
+
+```js
+// "react/jsx-no-literals": [<enabled>, {"noStrings": true, "elementOverrides": { "Button": {"noStrings": false} }}]
+// OR
+// "react/jsx-no-literals": [<enabled>, {"noStrings": true, "elementOverrides": { "Button": {} }}]
+
+var test = 'test'
+var Hello = <div>{test}</div>;
+var World = <Button>{'test'}</Button>;
+```
