&lt;p&gt;&lt;b&gt;New page&lt;/b&gt;&lt;/p&gt;&lt;div&gt;An [[Documentation/{{documentation/version}}/Extensions|extension]] could be seen as a delivery package bundling together one or more Slicer [[Documentation/{{documentation/version}}/Developers/Modules|modules]]. After installing an extension, the associated [[Documentation/{{documentation/version}}/Developers/Modules|modules]] will be presented to the user as built-in ones&lt;br /&gt;
&lt;br /&gt;
The Slicer community maintains a website referred to as the [http://slicer.kitware.com/midas3/slicerappstore Slicer Extensions Catalog] to support [[Documentation/{{documentation/version}}/SlicerApplication/ExtensionsManager#Installing_an_extension|finding, downloading and installing]] of extensions. Access to this [http://slicer.kitware.com/midas3/slicerappstore website] is integral to Slicer and facilitated by the [[Documentation/{{documentation/version}}/SlicerApplication/ExtensionsManager|Extensions Manager]] functionality built into the [http://download.slicer.org distributed] program. &lt;br /&gt;
&lt;br /&gt;
The [http://slicer.kitware.com/midas3/slicerappstore Catalog] classifies extensions into [[Documentation/{{documentation/version}}/Extensions/CatalogPolicies#Requirements_for_Category_1_Slicer_Extensions|three levels of compliance]]:&lt;br /&gt;
&lt;br /&gt;
# Category 1: Fully compliant Slicer Extensions: [http://www.slicer.org/pages/LicenseText Slicer license], [https://en.wikipedia.org/wiki/Open_source open source], maintained.&lt;br /&gt;
# Category 2: [https://en.wikipedia.org/wiki/Open_source Open source], contact exists.&lt;br /&gt;
# Category 3: All other extensions (work in progress, beta, closed source etc).&lt;br /&gt;
&lt;br /&gt;
To publish extensions, developers should consider reading the following pages:&lt;br /&gt;
* [[Documentation/{{documentation/version}}/Developers/Tutorials/BundleModulesIntoExtension|Bundle module(s) into a Slicer extension]]&lt;br /&gt;
* [[Documentation/{{documentation/version}}/Developers/Tutorials/BuildTestPackageDistributeExtensions|Build, test, package and distribute extensions]]&lt;/div&gt;</summary>
