 <h2>Getting started on Track Hubs</h2>
 <p>
 Track hubs are web-accessible directories of genomic data that can be viewed on the UCSC Genome 
 Browser alongside native annotation tracks. Hubs are a useful tool for visualizing a large number 
 of genome-wide data sets. The <a href="../../cgi-bin/hgHubConnect" target="_blank">Track Hub</a> 
 utility allows efficient access to data sets from around the world through the familiar Genome 
 Browser interface. Browser users can display tracks from any public track hub that has been 
 registered with UCSC. Additionally, users can import data from unlisted hubs or can set up, display,
 and share their own track hubs.</p>
 <p>
 For information on using the Track Hub features, refer to the <a href="hgTrackHubHelp.html">Genome 
 Browser Track Hub User Guide</a>. For specific information on configuring your trackDb.txt file, 
 refer to the <a href="trackDb/trackDbHub.html">Track Database Definition Document</a>. See also the

 <h2>Track Hubs in a single file</h2>
 <p>
 Historically, a hub needed a set of text files to specify properties for a track hub and each of
 the data tracks within the hub. The track hub settings were stored in a three file structure:
 hub.txt, genomes.txt, and trackDb.txt</p>
 <pre>
 myHub/          - directory containing track hub files
 * hub.txt       - a short description of hub properties
 * genomes.txt   - list of genome assemblies included in the hub data
 * hg19/         - directory of data for the hg19 (GRCh37) human assembly
 ** trackDb.txt  - display properties for tracks in this directory
 </pre>
