 The [Run MATLAB Command](#run-matlab-command) action enables you to execute MATLAB® scripts, functions, and statements on a [GitHub®-hosted](https://docs.github.com/en/actions/using-github-hosted-runners/about-github-hosted-runners/about-github-hosted-runners) or [self-hosted](https://docs.github.com/en/actions/hosting-your-own-runners/managing-self-hosted-runners/about-self-hosted-runners) runner:
 - To use a GitHub-hosted runner, include the [Setup MATLAB](https://github.com/matlab-actions/setup-matlab/) action in your workflow to set up your preferred MATLAB release (R2021a or later) on the runner.
-- To use a self-hosted runner, set up a computer with MATLAB on its path to host your runner and register the runner with GitHub Actions. (On self-hosted UNIX® runners, you can also use the **Setup MATLAB** action instead of having MATLAB installed.) The runner uses the topmost MATLAB release on the system path to execute your workflow.
+- To use a self-hosted runner, set up a computer with MATLAB on its path and register the runner with GitHub Actions. (On self-hosted UNIX® runners, you can also use the **Setup MATLAB** action instead of having MATLAB already installed.) The runner uses the topmost MATLAB release on the system path to execute your workflow.
 
 ## 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.
