+Please Note: GitHub hosted runners have some versions of the .NET SDK
 preinstalled. Installed versions are subject to change. Please refer to the
 documentation
 [software installed on github hosted runners](https://docs.github.com/en/actions/using-github-hosted-runners/about-github-hosted-runners#supported-software)

 - run: dotnet build <my project>
 ```
+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

 - run: dotnet build <my project>
 ```
-> **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.
-
-## 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)
-
-
-## 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' and 'A.x' 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.

-## 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: cp310
-      with:
-        dotnet-version: 3.1.422
-    - run: echo '${{ steps.cp310.outputs.dotnet-version }}' # outputs 3.1.422
-```
-
-**Multiple version installation**
-
-In case of a multiple version installation, the `dotnet-version` output contains the latest version that is installed by the action.
-
-```yaml
-    - uses: actions/setup-dotnet@v3
-      id: cp310
-      with:
-        dotnet-version: | 
-          3.1.422
-          5.0.408
-    - run: echo '${{ steps.cp310.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: cp310
-      with:
-        dotnet-version: |
