 for .NET SDK versions that are currently available.
 
-## Usage
+# Usage
 
 See [action.yml](action.yml)
 
-**Basic**:
+Basic:
 ```yaml
 steps:
 - uses: actions/checkout@v3
-- uses: actions/setup-dotnet@v3
+- uses: actions/setup-dotnet@v2
   with:
-    dotnet-version: '3.1.x'
+    dotnet-version: '3.1.x' # SDK Version to use; x will use the latest version of the 3.1 channel
 - run: dotnet build <my project>
 ```
-> **Warning**: Unless a concrete version is specified in the [`global.json`](https://learn.microsoft.com/en-us/dotnet/core/tools/global-json) file, **_the latest .NET version installed on the runner (including preinstalled versions) will be used [by default](https://learn.microsoft.com/en-us/dotnet/core/versions/selection#the-sdk-uses-the-latest-installed-version)_**. Please refer to the [documentation](https://docs.github.com/en/actions/using-github-hosted-runners/about-github-hosted-runners#supported-software) for the currently preinstalled .NET SDK versions.
+Multiple versions:
+> Note: In case multiple versions are installed, the latest .NET version will be used by default unless another version is specified in the `global.json` file.
 
-**Multiple version installation**:
 ```yml
 steps:
 - uses: actions/checkout@v3
 - name: Setup dotnet
-  uses: actions/setup-dotnet@v3
+  uses: actions/setup-dotnet@v2
   with:
     dotnet-version: | 
       3.1.x
       5.0.x
 - run: dotnet build <my project>
 ```
-## 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). 
-
-
-## Using the `dotnet-quality` input
-This input sets up the action to install the latest build of the specified quality in the channel. The possible values of `dotnet-quality` are: **daily**, **signed**, **validated**, **preview**, **ga**.
-
-> **Note**: `dotnet-quality` input can be used only with .NET SDK version in 'A.B', 'A.B.x', 'A', 'A.x' and 'A.B.Cxx' formats where the major version is higher than 5. In other cases, `dotnet-quality` input will be ignored.
-
+Preview version:
 ```yml
 steps:
 - uses: actions/checkout@v3
-- uses: actions/setup-dotnet@v3
+- uses: actions/setup-dotnet@v2
   with:
     dotnet-version: '6.0.x'
-    dotnet-quality: 'preview'
+    include-prerelease: true
 - run: dotnet build <my project>
 ```
-
-## Using the `global-json-file` input
-`setup-dotnet` action can read .NET SDK version from a `global.json` file. Input `global-json-file` is used for specifying the path to the `global.json`. If the file that was supplied to `global-json-file` input doesn't exist, the action will fail with error.
-
->**Note**: In case both `dotnet-version` and `global-json-file` inputs are used, versions from both inputs will be installed.
-
+global.json in a subdirectory:
 ```yml
 steps:
 - uses: actions/checkout@v3
-- uses: actions/setup-dotnet@v3
+- uses: actions/setup-dotnet@v2
   with:
     global-json-file: csharp/global.json
 - run: dotnet build <my project>
   working-directory: csharp
 ```
 
-## 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.
-
+Matrix Testing:
 ```yaml
-steps:
-- uses: actions/checkout@v3
-- uses: actions/setup-dotnet@v3
-  with:
-    dotnet-version: 6.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.
-
-```xml
-<PropertyGroup>
-  <DisableImplicitNuGetFallbackFolder>true</DisableImplicitNuGetFallbackFolder>
-</PropertyGroup>
-```
-
-### Reduce caching size
-
-> **Note**: Use [`NUGET_PACKAGES`](https://learn.microsoft.com/nuget/reference/cli-reference/cli-ref-environment-variables) environment variable if available. Some action runners already has huge libraries. (ex. Xamarin)
-
-```yaml
-env:
-  NUGET_PACKAGES: ${{ github.workspace }}/.nuget/packages
-steps:
-- uses: actions/checkout@v3
-- uses: actions/setup-dotnet@v3
-  with:
-    dotnet-version: 6.x
-    cache: true
-- run: dotnet restore --locked-mode
-```

-## Outputs
-
-### `dotnet-version`
-
-Using the **dotnet-version** output it's possible to get the installed by the action .NET SDK version. 
-
-**Single version installation**
-
-In case of a single version installation, the `dotnet-version` output contains the version that is installed by the action.
-
-```yaml
-    - uses: actions/setup-dotnet@v3
-      id: stepid
-      with:
-        dotnet-version: 3.1.422
-    - run: echo '${{ steps.stepid.outputs.dotnet-version }}' # outputs 3.1.422
-```
-
-**Multiple version installation**
-
-In case of a multiple version installation, the `dotnet-version` output contains the latest version that is installed by the action.
-
-```yaml
-    - uses: actions/setup-dotnet@v3
-      id: stepid
-      with:
-        dotnet-version: | 
-          3.1.422
-          5.0.408
-    - run: echo '${{ steps.stepid.outputs.dotnet-version }}' # outputs 5.0.408
-```
-**Installation from global.json**
-
-When the `dotnet-version` input is used along with the `global-json-file` input, the `dotnet-version` output contains the version resolved from the `global.json`.
-
-```yaml
-    - uses: actions/setup-dotnet@v3
-      id: stepid
-      with:
-        dotnet-version: |

-## Environment variables
+## Environment Variables to use with dotnet
 
 Some environment variables may be necessary for your particular case or to improve logging. Some examples are listed below, but the full list with complete details can be found here: https://docs.microsoft.com/en-us/dotnet/core/tools/dotnet-environment-variables
 
-| **Env.variable**      | **Description** | **Default value** |
-| ----------- | ----------- | ----------- |
-| DOTNET_INSTALL_DIR      |Specifies a directory where .NET SDKs should be installed by the action.|*default value for each OS* |
-| DOTNET_NOLOGO      |Removes logo and telemetry message from first run of dotnet cli|*false*|
-| DOTNET_CLI_TELEMETRY_OPTOUT   |Opt-out of telemetry being sent to Microsoft|*false*|
-| DOTNET_MULTILEVEL_LOOKUP   |Configures whether the global install location is used as a fall-back|*true*|
-| NUGET_PACKAGES |Configures a path to the [NuGet `global-packages` folder](https://learn.microsoft.com/nuget/consume-packages/managing-the-global-packages-and-cache-folders)|*default value for each OS* |
+- DOTNET_NOLOGO - removes logo and telemetry message from first run of dotnet cli (default: false)
+- DOTNET_CLI_TELEMETRY_OPTOUT - opt-out of telemetry being sent to Microsoft (default: false)
+- DOTNET_MULTILEVEL_LOOKUP - configures whether the global install location is used as a fall-back (default: true)
 
-The default values of the `DOTNET_INSTALL_DIR` and `NUGET_PACKAGES` environment variables depend on the operation system which is used on a runner:
-| **Operation system** | `DOTNET_INSTALL_DIR` | `NUGET_PACKAGES` |
-| ----------- | ----------- | ----------- |
-| **Windows** | `C:\Program Files\dotnet` | `%userprofile%\.nuget\packages` |
-| **Ubuntu** | `/usr/share/dotnet` | `~/.nuget/packages` |
-| **macOS** | `/Users/runner/.dotnet` | `~/.nuget/packages` |
-
-**Example usage of environment variable**:
-```yml
+Example usage:
+```yaml
 build:
   runs-on: ubuntu-latest
   env:
-    DOTNET_INSTALL_DIR: "path/to/directory"
-    NUGET_PACKAGES: ${{ github.workspace }}/.nuget/packages
