 # Action for Running MATLAB Commands
 
-The [Run MATLAB Command](#run-matlab-command) action enables you to execute MATLAB® scripts, functions, or statements 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 (R2013b or later) 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™.
+The [Run MATLAB Command](#run-matlab-command) action enables you to execute MATLAB® scripts, functions, and statements on a self-hosted or GitHub®-hosted runner. The action uses the topmost MATLAB version on the system path.
 
 ## Examples
 Use the **Run MATLAB Command** action to run MATLAB scripts, functions, and statements. You can use this action to flexibly customize your test run or add a step in MATLAB to your workflow.
 
 ### Run MATLAB Script on Self-Hosted Runner
-Use a self-hosted runner to run the commands in a file named `myscript.m` in the root of your repository.

 ### Run MATLAB Commands on GitHub-Hosted Runner
-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 Command
-When you define your workflow in the `.github/workflows` directory of your repository, specify the **Run MATLAB Command** action as `matlab-actions/run-command@v1`. The action requires an input and also accepts an optional input.

If you specify more than one script, function, or statement, use a comma or semicolon to separate them.<br/>MATLAB exits with exit code 0 if the specified script, function, or statement executes successfully without error. Otherwise, MATLAB terminates with a nonzero exit code, which causes the build to fail.
