+<h2>Dec. 16, 2021 &nbsp;&nbsp; Track Hub Filters Quick Start Guide</h2>
+<p>
+We are pleased to announce a help page specific to building filters on Track Hubs.
+<a href="help/hgTrackHubHelp.html#Intro">Track Hubs</a> are web-accessible directories of
+genomic data that can be viewed on the UCSC Genome Browser. Track Hubs allow a lab to share and
+host all their genomic data (<a href="help/bam.html">BAMs</a>, <a href="help/vcf.html">VCFs</a>,
+ect.) via a single Genome Browser link. Such links can load multiple hubs and even be combined with
+a position parameter to easily reference laboratory data around a gene of interest, see examples in
+a recent <a href="https://bit.ly/UCSC_blog_sharing">blog bost</a> about sharing data with URLs.</p>
+<p>
+The <a href="help/hubQuickStartFilter.html">Track Hub Filters Quick Start Guide</a> provides example
+hubs employing new extensive <a href="help/trackDb/trackDbHub.html#filter">filter</a> settings
+available for Track Hubs.</p>
+<p>
+The help page is divided into three sections:
+<ul>
+<li>filter.fieldName - Used for numerical data</li>
+<li>filterText.fieldName - Used for text filtering</li>
+<li>filterValues.fieldName - Used for filtering by pre-specified values or categories in data</li>
+</ul></p>
+<p>
+The <a href="help/hubQuickStartFilter.html#filterText">filterText.fieldName</a> section discusses
+settings that allow to filter items in a hub with names as seen with this screenshot of only
+displaying items starting with BRCA using the wildcard match &quot;BRCA*&quot;.</p>
+<p class ="text-center">
+  <a href="https://genome.ucsc.edu/s/Lou/filterTextExample1">
+    <img class="text-center" src="help/examples/hubQuickStartFilter/filterTextExample1.1.png" width="800px">
+    <img class="text-center" src="help/examples/hubQuickStartFilter/filterTextExample1.2.png" width="45%">
+  </a>
+</p>
+<p>
+The <a href="help/hubQuickStartFilter.html#filterValues">filterValues.fieldName</a> section discusses
+how to display a drop-down list of options to select items as seen with this screenshot of filtering
+items that are labeled as either a &quot;DNA-binding region&quot; or &quot;alpha helix&quot; or
+&quot;beta strand&quot;.</p>
+<p class ="text-center">
+  <a href="http://genome.ucsc.edu/s/Lou/filterValuesExample2">
+    <img class="text-center" src="help/examples/hubQuickStartFilter/filterValuesExample2.1.png" width="800px">
+    <img class="text-center" src="help/examples/hubQuickStartFilter/filterValuesExample2.2.png" width="45%">
+  </a>
+</p>
+<p>
+Each section of the <a href="help/hubQuickStartFilter.html">Track Hub Filters Quick Start Guide</a>
+comes with examples and sessions allowing to quickly click into real interactive
+demonstration hubs to experiment with how the settings work. The example hubs also provide a
+starter template for building similar hubs.</p>
+<p>
+Many thanks to Lou Nassar for building this Filters Quick Start Guide and Brian Raney for
+his work implementing the new filter software.</p>
