 ## Requirements
 
-- A desktop platform with the [.NET Core SDK 2.2](https://www.microsoft.com/net/learn/get-started) or higher installed.
+- A desktop platform with the [.NET Core SDK 3.0](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 Community Edition](https://www.visualstudio.com/) (Windows), [Visual Studio Code](https://code.visualstudio.com/) (with the C# plugin installed) or [Jetbrains Rider](https://www.jetbrains.com/rider/) (commercial).
