 This page focuses on the settings found in the <a target="_blank"
 href="../hgTrackHubHelp.html#trackDb.txt"><code>trackDb.txt</code></a> file used in
 both Track Hubs and Assembly Hubs; however, this page does not describe the settings unique to
 Assembly Hubs. Track Hubs can display novel genomes, through a type of hub called an
 <a href="../hgTrackHubHelp.html#Assembly" target="_blank">Assembly Hub</a>.
 The <a href="../hgTrackHubHelp.html#example_genomes.txt"
 target="_blank"><code>genomes.txt</code></a> file for an Assembly Hub involves
 many additional settings not described on this page, such as
 <a href="../hgTrackHubHelp.html#twoBitPath" target="_blank"><code>twoBitPath</code></a> and
 <a href="../hgTrackHubHelp.html#defaultPos" target="_blank"><code>defaultPos</code></a> to
 identify the location of the sequence for the novel assembly and what default position to
 display. The <code>genomes.txt</code> file in Assembly Hubs also requires display information
 such as <a href="../hgTrackHubHelp.html#organism" target="_blank"><code>organism</code></a>,
 <a href="../hgTrackHubHelp.html#scientificName" target="_blank"><code>scientificName</code></a>,
 <a href="../hgTrackHubHelp.html#description" target="_blank"><code>description</code></a>,
+<a href="../hgTrackHubHelp.html#orderKey" target="_blank"><code>orderKey</code></a>,
 and <a href="../hgTrackHubHelp.html#htmlPath" target="_blank"><code>htmlPath</code></a> to
 label the novel assembly on the gateway page. A special <a href="../hgTrackHubHelp.html#groups"
 target="_blank"><code>groups</code></a> setting in Assembly Hubs points to a separate text
 document that defines track groups under the main image (such as the first &quot;Mapping and
 Sequencing&quot; group found on almost all Browsers). Read the <a target="_blank"
 href="../hgTrackHubHelp.html#genomes.txt">&quot;Create the genomes.txt file&quot;</a> section
 of the Track Hub User Guide for more information, and see examples in the <a target="_blank"
 href="../hubQuickStartAssembly.html" target="_blank">Quick Start Guide to Assembly Hubs<a>.</p>
