 <p>
 Visualizing VCF files in hubs involves creating three text files: <em>hub.txt</em>, 
 <em>genomes.txt</em>, and <em>trackDb.txt</em>. The browser is passed a URL to the top-level 
 <em>hub.txt</em> file that points to the related <em>genomes.txt</em> and <em>trackDb.txt</em> 
 files. The <em>trackDb.txt</em> file contains stanzas for each track that outlines the details 
 and type of each track to display, such as these lines for a VCF file located at the bigDataUrl 
 location:</p>
 <pre><code>track vcf1
 bigDataUrl http://hgdownload.soe.ucsc.edu/gbdb/hg19/1000Genomes/ALL.chr21.integrated_phase1_v3.20101123.snps_indels_svs.genotypes.vcf.gz
 #Note: there is a corresponding fileName.vcf.gz.tbi in the same above directory
 shortLabel chr21 VCF example
 longLabel This chr21 VCF file is an example from the 1000 Genomes Phase 1 Integrated Variant Calls Track
 type vcfTabix
 visibility dense </code></pre>
 <p>
+<b>Note:</b> there is now a <code>useOneFile on</code> hub setting that allows the hub
+properties to be specified in a single file. More information about this setting can be found on the
+<a href="./hgTracksHelp.html#UseOneFile" target="_blank">Genome Browser User Guide</a>.</p>
+<p>
 Here is a direct link to the <em><a href="examples/hubDirectory/hg19/trackDb.txt" 
 target="_blank">trackDb.txt</a></em> file to see more information about this example hub, and below 
 is a direct link to visualize the hub in the browser, where this example VCF file displays in dense 
 mode alongside the other tracks in this hub. You can find more Track Hub VCF display options on the 
 <a href="trackDb/trackDbHub.html#vcfTabix" target="_blank">Track Database (trackDb) Definition 
 Document</a> page.</p>
