+# Extensions List
+
+DataFusion tries to provide a good set of features "out of the box" to quickly
+start with a working system, but it can't include every useful feature (e.g.
+`TableProvider`s for all data formats).
+
+Thankfully one of the core features of DataFusion is a flexible extension API
+that allows users to extend its behavior at all points. This page lists some
+community maintained extensions available for DataFusion. These extensions are
+not part of the core DataFusion project, and not under Apache Software
+Foundation governance but we list them here to be useful to others in the
+community.
+
+If you know of an available extension that is not listed below, please open a 
PR
+to add it to this page. If there is some feature you would like to see in
+DataFusion, please consider creating a new extension in the 
`datafusion-contrib`
+project (see [below](#datafusion-contrib)). Please [contact] us via github 
issue, slack, or Discord and
+we'll gladly set up a new repository for your extension.

+<p>DataFusion tries to provide a good set of features “out of the box” to 
quickly
+start with a working system, but it can’t include every useful feature (e.g.
+<code class="docutils literal notranslate"><span 
class="pre">TableProvider</span></code>s for all data formats).</p>
+<p>Thankfully one of the core features of DataFusion is a flexible extension 
API
+that allows users to extend its behavior at all points. This page lists some
+community maintained extensions available for DataFusion. These extensions are
+not part of the core DataFusion project, and not under Apache Software
+Foundation governance but we list them here to be useful to others in the
+community.</p>
+<p>If you know of an available extension that is not listed below, please open 
a PR
+to add it to this page. If there is some feature you would like to see in
+DataFusion, please consider creating a new extension in the <code 
class="docutils literal notranslate"><span 
class="pre">datafusion-contrib</span></code>
+project (see <a class="reference internal" 
href="#datafusion-contrib">below</a>). Please <a class="reference internal" 
href="../contributor-guide/communication.html"><span class="std 
std-doc">contact</span></a> us via github issue, slack, or Discord and
+we’ll gladly set up a new repository for your extension.</p>
