|ext_short| Overview
====================

Overview Content
----------------

|ext| are the core building blocks of |kit|__-based |applications_short|. These make up the individual tools you use within |composer|__, |presenter|__, |mach_short|__, and other |apps_short|. Because |kit_short|-based |apps_short| are composed of |ext_short|, you can extend the functionality of the |apps_short| you use to meet your needs by creating new |ext_short| or editing or activating existing ones.

|ext_short| List
----------------

The |ext_short| listed in this portal are organized under "top level" |ext_short|. For example, `Physics <../../extensions/physics.html>`__ is not a singular, monolithic Extension. Instead, it's a group of |ext_short| comprising the complete Physics simulation toolset. As individual parts, the |ext_short| would be difficult to document. Therefore, this list is simplified for usage and training purposes.

Building |ext_short|
--------------------

|ext_short| are powerful tools for developing critical infrastructure to pipelines, augmenting workflows, and adding functionality to |omni|. Read our `Extension development guide <https://docs.omniverse.nvidia.com/kit/docs/kit-manual/latest/guide/extensions_basic.html>`__ to get started.
