 This guide contains steps required to allow compilation of Cataclysm-DDA on Windows using Visual Studio and vcpkg.
 
-Steps from current guide were tested on Windows 10 (64 bit), Visual Studio 2017 (64 bit) and vcpkg, but should as well work with slight modifications for other versions of Windows and Visual Studio.

 ## Prerequisites:
 
 * Computer with modern Windows operating system installed (Windows 10, Windows 8.1 or Windows 7);
 * NTFS partition with ~15 Gb free space (~10 Gb for Visual Studio, ~1 Gb for vcpkg installation, ~3 Gb for repository and ~1 Gb for build cache);
 * Git for Windows (installer can be downloaded from [Git homepage](https://git-scm.com/));
-* Visual Studio 2017 (or 2015 Visual Studio Update 3 and above);
+* Visual Studio 2019 (or 2015 Visual Studio Update 3 and above);
 * Latest version of vcpkg (see instructions on [vcpkg homepage](https://github.com/Microsoft/vcpkg)).
 
 **Note:** Windows XP is unsupported!

 ### Debugging
 
-After building Cataclysm, you may discover that after pressing the debug button in Visual Studio, Cataclysm just exits after launch with return code 1. That is because of the wrong working directory. You need to configure the working directory to `$(ProjectDir)..`.
+Ensure that the Cataclysm project (`Cataclysm-vcpkg-static`) is the selected startup project, configure the working directory in the project settings to `$(ProjectDir)..`, and then press the debug button (or use the appropriate shortcut, e.g. F5).

 When debugging, it is not strictly necessary to use a `Debug` build; `Release` builds run significantly faster, can still be run in the debugger, and most of the time will have most of the information you need.
 
+### Running unit tests
+
+Ensure that the Cataclysm test project (`Cataclysm-test-vcpkg-static`) is the selected startup project, configure the working directory in the project settings to `$(ProjectDir)..`, and then press the debug button (or use the appropriate shortcut, e.g. F5). This will run all of the unit tests. Additional command line arguments may be configured in the project's command line arguments setting, or if you are using a compatible unit test runner (e.g. Resharper) you can run or debug individual tests from the unit test sessions.

 ### Make a distribution
 
 There is a batch script in `msvc-full-features` folder `distribute.bat`. It will create a sub folder `distribution` and copy all required files(eg. `data/`, `Cataclysm.exe` and dlls) into that folder. Then you can zip it and share the archive on the Internet.
