 ## Requirements
 
 - A desktop platform with the [.NET Core SDK 2.2](https://www.microsoft.com/net/learn/get-started) or higher installed.
+- When running on linux, please have a system-wide ffmpeg installation available to support video decoding.
+- When running on Windows 7 or 8.1, **[additional prerequisites](https://docs.microsoft.com/en-us/dotnet/core/windows-prerequisites?tabs=netcore2x)** may be required to correctly run .NET Core applications if your operating system is not up-to-date with the latest service packs.
 - When working with the codebase, we recommend using an IDE with intellisense and syntax highlighting, such as [Visual Studio 2017+](https://visualstudio.microsoft.com/vs/), [Jetbrains Rider](https://www.jetbrains.com/rider/) or [Visual Studio Code](https://code.visualstudio.com/).
-- Note that there are **[additional requirements for Windows 7 and Windows 8.1](https://docs.microsoft.com/en-us/dotnet/core/windows-prerequisites?tabs=netcore2x)** which you may need to manually install if your operating system is not up-to-date.
