 Starting in R2022b, the MATLAB® build tool provides a standard programming interface to create and run software-build tasks in a uniform and efficient way. For example, you can create tasks that identify code issues, run tests, and package a toolbox in a single build file in your project root folder, and then invoke the build tool to run these tasks. For more information, see [Overview of MATLAB Build Tool](https://www.mathworks.com/help/matlab/matlab_prog/overview-of-matlab-build-tool.html).
 
-The [Run MATLAB Build](#run-matlab-build) action enables you to invoke the MATLAB build tool on a [self-hosted](https://docs.github.com/en/free-pro-team@latest/actions/hosting-your-own-runners/about-self-hosted-runners) or [GitHub®-hosted](https://docs.github.com/en/free-pro-team@latest/actions/reference/specifications-for-github-hosted-runners) runner:
-
-- To use a self-hosted runner, you must set up a computer with MATLAB as your runner. The runner uses the topmost MATLAB version on the system path to execute your workflow.
-
-- To use a GitHub-hosted runner, you must include the [Setup MATLAB](https://github.com/matlab-actions/setup-matlab/) action in your workflow to set up MATLAB on the runner. Currently, this action is available only for public projects. It does not set up transformation products, such as MATLAB Coder™ and MATLAB Compiler™.

 ## Examples
-Use the **Run MATLAB Build** action to run a build using the MATLAB build tool. You can use this action to run the tasks specified in a file named  `buildfile.m` in the root of your repository.

-Before you run MATLAB code or Simulink models on a GitHub-hosted runner, first use the [Setup MATLAB](https://github.com/matlab-actions/setup-matlab/) action. The action sets up your specified MATLAB release (R2020a or later) on a Linux® virtual machine. If you do not specify a release, the action sets up the latest release of MATLAB.

 ## Run MATLAB Build

 ## Notes
-* The **Run MATLAB Build** action uses the `-batch` option to invoke the [`buildtool`](https://www.mathworks.com/help/matlab/ref/buildtool.html) command noninteractively. Preferences do not persist across different MATLAB sessions launched with the `-batch` option. To run code that requires the same preferences, use a single action.
