 ## Supported version syntax
 
 The `dotnet-version` input supports following syntax:
 
-- **A.B.C** (e.g 6.0.400, 7.0.100-preview.7.22377.5) - installs exact version of .NET SDK
-- **A.B** or **A.B.x** (e.g. 3.1, 3.1.x) - installs the latest patch version of .NET SDK on the channel `3.1`, including prerelease versions (preview, rc)
-- **A** or **A.x** (e.g. 3, 3.x) - installs the latest minor version of the specified major tag, including prerelease versions (preview, rc)
-- **A.B.Cxx** (e.g. 6.0.4xx) - available since `.NET 5.0` release. Installs the latest version of the specific SDK release, including prerelease versions (preview, rc). 
+- **A.B.C** (e.g 9.0.308, 10.0.100-preview.1.25120.13) - installs exact version of .NET SDK
+- **A.B** or **A.B.x** (e.g. 8.0, 8.0.x) - installs the latest patch version of .NET SDK on the channel `8.0`, including prerelease versions (preview, rc)
+- **A** or **A.x** (e.g. 8, 8.x) - installs the latest minor version of the specified major tag, including prerelease versions (preview, rc)
+- **A.B.Cxx** (e.g. 8.0.4xx) - available since `.NET 5.0` release. Installs the latest version of the specific SDK release, including prerelease versions (preview, rc). 
 
 
+## Using the `architecture` input
+Using the architecture input, it is possible to specify the required .NET SDK architecture. Possible values:  `x64`, `x86`, `arm64`, `amd64`, `arm`, `s390x`, `ppc64le`, `riscv64`. If the input is not specified, the architecture defaults to the host OS architecture (not all of the architectures are available on all platforms).
+
+**Example: Install multiple SDK versions for a specific architecture**
+```yml

+The `workloads` input allows you to install .NET workloads as part of the SDK setup. Workloads provide additional platform tools and dependencies for frameworks. This action automatically runs `dotnet workload update` before installing the specified workloads to ensure manifests are refreshed and existing workloads are updated to their latest compatible versions.

+
+> **Note**: Ensure workloads are compatible with your runner's OS, architecture, and .NET SDK version before enabling workload installation. Some workloads may require additional installation time due to large toolchain downloads.
