  \<p>A set of tools that allows a developer to build a custom application that integrates with or connects to a platform or service.\</p>
  \</div>)* for C `README.md`, which contains information developers need to develop agents using the SDK. It also contains `ReadMeFirst.pdf` and `Legal.pdf`, which contain general information about the kit and third-party licenses used by components of the SDK.

* `/apidocs`

  API documentation for the SDK. Open `index.html` to access the API documentation content.

* `/include`

  Agent SDK header files.

* `/lib`

  32-bit and 64-bit libraries for Red Hat Enterprise Linux 7 and 8, and Windows, including third-party dependencies required by the SDK.
