Simply install the module using the standard method.

To add the button to the GridField you need to extend ModelAdmin and override getEditForm() method like this:

function getEditForm($id = null, $fields = null) {
	$form = parent::getEditForm();

	$form
		->Fields()
		->fieldByName($this->sanitiseClassName($this->modelClass))
		->getConfig()
		->addComponent(new CopyButton(), 'GridFieldEditButton') // or just ->addComponent(new CopyButton())
	;

	return $form;
}

This action will make exact copy of the record (with all relations and etc.). Note: you have to set configs for cascading duplications in your DataObjects to duplicate relations See: https://docs.silverstripe.org/en/4/developer_guides/model/relations/#cascading-duplications

Sometimes you will need to do some actions just after copy operation (i.e. you'll need to remove some relations). It is easily achieved by extending DataObject and writing all the actions in the onAfterDuplicate() method.

class SomeObjectExtension extends DataExtension {

	public function onAfterDuplicate() {
		DB::query("delete from Member_SomeObject where SomeObjectID = ".$this->owner->ID);
	}

}
