 The latest stable binaries are found at [.NET downloads](https://dotnet.microsoft.com/download). If you wish to use the latest (and potentially unstable) pre-release tooling, use the links provided at the [dotnet/installer GitHub repository](https://github.com/dotnet/installer#installers-and-binaries). For Linux distributions, `tar.gz` archives (also known as `tarballs`) are available; use the installation scripts within the archives to install .NET.
