Documentation/Nightly/Developers/Extensions/Index

Think of the ExtensionsIndex as a repository containing a list of extension description files (*.s4ext) used by the Slicer extensions build system to build, test, package and upload extensions on an extensions server.

Once uploaded on an extensions server, within Slicer, extensions can be installed using the extensions manager.

The extensions catalog provides Slicer users with a convenient way to access the extensions previously uploaded.
