 title: "Genome Browser Documentation"
 ---
 
 The Genome Browser offers a web-based interface for visualizing genomic data on
 a variety of genome assemblies. If you're new here, the tutorials below are
 the fastest way to get started.
 
 ## Tutorials
 
 | Tutorial | Description |
 | - | - |
 | [Genome Browser Basics](/docs/tutorials/gb101.html) | Learn the basics of the Genome Browser interface |
 | [Gateway Page](/docs/tutorials/gatewayTutorial.html) | Find and switch between genome assemblies |
 | [Table Browser](/docs/tutorials/tableBrowserTutorial.html) | Query and download Genome Browser data |
 | [Custom Tracks](/docs/tutorials/customTrackTutorial.html) | Display your own annotations in the Genome Browser |
 
 Take a look at our [training slides](/docs/browserSlideDecks.html) for more walk-throughs of Genome Browser features, 
 including cancer data and variant analysis.
 
 Prefer video? Our [training page](/training/index.html) has short how-to
 videos on common tasks like saving sessions, using BLAT and isPCR, and
 finding SNPs in a gene.
 
 Looking up a term you don't recognize? Check our
 [glossary](/docs/genomeBrowserGlossary.html).
 
 ## Visualize your own data
 
 Display your own annotations alongside the data we host:
 
 - [Custom tracks](/cgi-bin/hgCustom) — the simpler option for displaying
   your own annotations. See our
   [documentation](/goldenPath/help/customTrack.html) to learn how to load
   your own.
 - [Track hubs](/cgi-bin/hgHubConnect#unlistedHubs) — more powerful and
   configurable, ideal for many tracks or for sharing data publicly. Start
   with our [Hub Basics](/docs/hubs/hubBasics.html) page, and validate your
   hub with our [hub development tools](/cgi-bin/hgHubConnect#hubDeveloper).
+  For hubs with thousands of subtracks, our
+  [Faceted Composite Tracks](/docs/hubs/facetedComposite.html) page covers a
+  filterable alternative to the standard composite interface.
 
 For both hubs and custom tracks, we provide storage through
 [hub space](/cgi-bin/hgHubConnect#hubUpload).
 
 ## Share your work
 
 Once you've configured a view, share it with collaborators or publish it
 broadly:
 
 - [Links](/FAQ/FAQlink.html) — share a snapshot of your current view as a URL.
 - [Sessions](/cgi-bin/hgSession) — save and share full Genome Browser
   configurations.
 - [Public hubs](/cgi-bin/hgHubConnect#publicHubs) — to contribute your own,
   see our [guidelines](/goldenPath/help/publicHubGuidelines.html).
 - [Contributed tracks](/docs/hubs/contributedTracks.html) — submit
   annotations on [GenArk](https://hgdownload.gi.ucsc.edu/hubs/) assemblies.
 
 ## Download data
 
 Access our underlying data outside the browser:
 
 - The [download server](https://hgdownload.gi.ucsc.edu/downloads.html)
   provides the data underlying the Genome Browser, plus pairwise alignments
   and LiftOver chain files.
 - Our [REST API](/goldenPath/help/api.html) returns data in JSON format.
 - [Command-line tools](https://hgdownload.gi.ucsc.edu/downloads.html#utilities_downloads)
   for working with bigBed, bigWig, and other formats, plus standalone
   versions of `liftOver`, `blat`, and others.
 
 ## Get help
 
 - [Contact us](/contacts.html) — email, mailing lists, and other support
   channels.
 - [FAQ](/FAQ/) — common questions, including
   [data file formats](/FAQ/FAQformat.html).
