This option enables both the usual OpenMP features, and OpenMP SIMD features not available when using the **`/openmp`** switch.
 
 Starting in Visual Studio 2019 version 16.9, you can use the experimental **`/openmp:llvm`** option instead of **`/openmp`** to target the LLVM OpenMP runtime. Support currently isn't available for production code, since the required libomp DLLs aren't redistributable. The option supports the same OpenMP 2.0 directives as **`/openmp`**. And, it supports all the SIMD directives supported by the **`/openmp:experimental`** option. It also supports unsigned integer indices in parallel for loops according to the OpenMP 3.0 standard. For more information, see [Improved OpenMP Support for C++ in Visual Studio](https://devblogs.microsoft.com/cppblog/improved-openmp-support-for-cpp-in-visual-studio/).

+The usual starting point for a C++ programmer is a "Hello, world!" application that runs on the command line. That's what you create in Visual Studio in this step.
 
 ## Prerequisites
 
 - Have Visual Studio with the Desktop development with C++ workload installed and running on your computer. If it's not installed yet, see [Install C++ support in Visual Studio](vscpp-step-0-installation.md).
 
 ## Create your app project
 
-Visual Studio uses *projects* to organize the code for an app, and *solutions* to organize your projects. A project contains all the options, configurations, and rules used to build your apps. It manages the relationship between all the project's files and any external files. To create your app, first, you'll create a new project and solution.

 If you don't see **Copy as path** in the shortcut menu, dismiss the menu, and then hold down the **Shift** key while you open it again. This command is just for convenience.
