# Instructions phases

Instruction phases allow you to build instructions into an experiment. You can

* Add a next or back button to your instruction — so a participant can move forward or backward through the instructions if they have not understood something. 
* Add a next button under every element so a participant can decide when to move onto the next screen in the experiment. 
* Display an instruction multiple times by setting the ‘loop’ option.  The phase can be ‘looped’ until the user clicks next or by a specified number of loops.
* Add a soundtrack overlay. 

All elements can be added to an instructions phase. However, there is less customization available in instruction phases — for example, you cannot change an element's duration in an instruction phase. <br>

#### How do I add a new instruction to an instruction phase?

To add a new instruction to an instructions phase, click on the + button on the instruction phase screen. When you click on the + button, a drop-down list will appear where you can choose one of the following elements to add to the phase:

* **Text** — Type and edit text that you want to include in the phase.&#x20;
* **Image** — Upload an image file or select a previously uploaded image you want to include in the phase. &#x20;
* **Audio** — Upload an audio file or select a previously uploaded audio file you want to include in the phase.&#x20;
* **Video** — Upload an audio file or select a previously uploaded audio file you want to include in the phase.&#x20;
* **Questionnaire** — Type questions, select the type of questions (multiple-choice, open text, etc.), input answers and choose how to display them in the phase.
