<p>This plugin is for showing instructions to the subject. It allows subjects to navigate through multiple pages of instructions at their own pace, recording how long the subject spends on each page. Navigation can be done using the mouse or keyboard. Subjects can be allowed to navigate forwards and backwards through pages, if desired.</p>
<h2 id="parameters">Parameters<a class="headerlink" href="#parameters" title="Permanent link">&para;</a></h2>
<p>In addition to the <a href="../overview/plugins#parameters-available-in-all-plugins">parameters available in all plugins</a>, this plugin accepts the following parameters. Parameters with a default value of <em>undefined</em> must be specified. Other parameters can be left unspecified if the default value is acceptable.</p>

<tbody>
<tr>
<td>view_history</td>
<td>array</td>
<td>An array containing the order of pages the subject viewed (including when the subject returned to previous pages) and the time spent viewing each page. Each object in the array represents a single page view, and contains keys called <code>page_index</code> (the page number, starting with 0) and <code>viewing_time</code> (duration of the page view). This will be encoded as a JSON string when data is saved using the <code>.json()</code> or <code>.csv()</code> functions.</td>
