# How to Use the App
As shown earlier, there are 3 ways to specify the object to count: (1) with text only, (2) with text and any number of boxes (i.e., "visual exemplars") around example objects, and (3) with visual exemplars only. What is being used is indicated in the top left of the output image. How to try each case is detailed below.
<ol>
<li><strong>Text Only: </strong> Only provide text describing the object to count in the textbox titled "What would you like to count?" Delete all boxes drawn on the visual exemplar image.</li>
<li><strong>Text + Visual Exemplars: </strong> Provide text describing the object to count in the textbox titled "What would you like to count?" and draw at least one box around an example object in the visual exemplar image.</li>
<li><strong>Visual Exemplars Only: </strong> Remove all text in the textbox titled "What would you like to count?" and draw at least one box around an example object in the visual exemplar image.</li>
