# 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>
