+# add-prop
+
+This universal codemod provides possibility to add any prop to any component.
+
+```diff
+- <Component />
++ <Component newProp="info" />
+
+```
+## Usage
+
+`npx carbon-codemod add-prop <target> <component-import-path> <prop> <value>`
+
+### Examples
+
+### String
+`npx carbon-codemod add-prop src carbon-react/lib/components/button ml "16px"`
+
+```diff
+- <Button>Button</Button>
++ <Button ml="16px">Button</Button>
+```
+
+### Number
+`npx carbon-codemod add-prop src carbon-react/lib/components/button ml 2`
+
+```diff
+- <Button>Button</Button>
++ <Button ml={2}>Button</Button>
+```
+
+### Boolean - True
+`npx carbon-codemod add-prop src carbon-react/lib/components/button hasBorder true`
+
+```diff
+- <Button>Button</Button>
++ <Button hasBorder>Button</Button>
+```
+
+### Boolean - False
