 ## 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
+steps:
+- uses: actions/checkout@v6
+- name: Setup dotnet (x86)

+## Caching NuGet Packages
+The action has a built-in functionality for caching and restoring dependencies. It uses [toolkit/cache](https://github.com/actions/toolkit/tree/main/packages/cache) under the hood for caching global packages data but requires less configuration settings. The `cache` input is optional, and caching is turned off by default.
+
+The action searches for [NuGet Lock files](https://learn.microsoft.com/nuget/consume-packages/package-references-in-project-files#locking-dependencies) (`packages.lock.json`) in the repository root, calculates their hash and uses it as a part of the cache key. If lock file does not exist, this action throws error. Use `cache-dependency-path` for cases when multiple dependency files are used, or they are located in different subdirectories.
+
+> **Warning**: Caching NuGet packages is available since .NET SDK 2.1.500 and 2.2.100 as the NuGet lock file [is available](https://learn.microsoft.com/nuget/consume-packages/package-references-in-project-files#locking-dependencies) only for NuGet 4.9 and above.

+  with:
+    dotnet-version: 8.x
+    cache: true
+- run: dotnet restore --locked-mode
+```
+
+> **Note**: This action will only restore `global-packages` folder, so you will probably get the [NU1403](https://learn.microsoft.com/nuget/reference/errors-and-warnings/nu1403) error when running `dotnet restore`.
+> To avoid this, you can use [`DisableImplicitNuGetFallbackFolder`](https://github.com/dotnet/reproducible-builds/blob/abfe986832aa28597d3340b92469d1a702013d23/Documentation/Reproducible-MSBuild/Techniques/DisableImplicitNuGetFallbackFolder.md) option.

+## Using the `workloads` input
+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.

+
