# Track Changes Track changes can be set on text elements. There are 2 ways to set the change information on an element. Either by calling the `setChangeInfo()`, or by setting the `TrackChange` instance on the element with `setTrackChange()`. ``` php addSection(); $textRun = $section->addTextRun(); $text = $textRun->addText('Hello World! Time to '); $text = $textRun->addText('wake ', array('bold' => true)); $text->setChangeInfo(TrackChange::INSERTED, 'Fred', time() - 1800); $text = $textRun->addText('up'); $text->setTrackChange(new TrackChange(TrackChange::INSERTED, 'Fred')); $text = $textRun->addText('go to sleep'); $text->setChangeInfo(TrackChange::DELETED, 'Barney', new \DateTime('@' . (time() - 3600))); ```
