-This action sets up a go environment for use in actions by:
+- Optionally downloading and caching a version of Go by version and adding to PATH
+- Registering problem matchers for error output
+- Providing intelligent caching for Go modules and build outputs
 
-- optionally downloading and caching a version of Go by version and adding to PATH
-- registering problem matchers for error output
+## Quick Start
 
-# V2
-
-The V2 offers:
-- Adds GOBIN to the PATH
-- Proxy Support
-- `stable` input 
-- Check latest version
-- Bug Fixes (including issues around version matching and semver)
-
-The action will first check the local cache for a version match. If a version is not found locally, it will pull it from the `main` branch of the [go-versions](https://github.com/actions/go-versions/blob/main/versions-manifest.json) repository. On miss or failure, it will fall back to downloading directly from [go dist](https://storage.googleapis.com/golang). To change the default behavior, please use the [check-latest input](#check-latest-version).
-
-Matching by [semver spec](https://github.com/npm/node-semver):
 ```yaml
 steps:
-  - uses: actions/checkout@v2
-  - uses: actions/setup-go@v2
+  - uses: actions/checkout@v5
+  - uses: actions/setup-go@v6
     with:
-      go-version: '^1.13.1' # The Go version to download (if necessary) and use.
+      go-version: '1.23'
   - run: go version
 ```
 
-Matching an unstable pre-release:
-```yaml
-steps:
-  - uses: actions/checkout@v2
-  - uses: actions/setup-go@v2
-    with:
-      stable: 'false'
-      go-version: '1.14.0-rc1' # The Go version to download (if necessary) and use.
-  - run: go version
+## Breaking Changes
+
+### V6 Changes
+
+#### Node Runtime Upgrade
+- **Upgraded from Node 20 to Node 24**
+- ⚠️ **Action Required**: Ensure your runner is on version v2.327.1 or later for compatibility
+- See [Release Notes](https://github.com/actions/runner/releases/tag/v2.327.1) for more details
+
+#### Enhanced Go Toolchain Management
+
+V6 introduces significant improvements for reliable and consistent Go version selection:
+
+**Toolchain Directive Support**
+Now correctly interprets both `go` and `toolchain` directives from `go.mod`:
+```go
+go 1.23.0           // Minimum required version
+toolchain go1.23.2  // V6 uses this exact version
 ```
 
-# Usage
+**Intelligent Caching**
+Cache keys now incorporate the `toolchain` directive version from `go.mod`, eliminating cache conflicts when switching between different toolchain versions within the same Go minor release.
 
-See [action.yml](action.yml)
+For more details, see the [full release notes](https://github.com/actions/setup-go/releases/tag/v6.0.0).
+
+### V5 Changes
+
+- **Upgraded Node.js runtime from node16 to node20**
+- See [full release notes](https://github.com/actions/setup-go/releases) for complete details
+
+## Version Resolution Behavior
+
+The action follows this resolution order:
+1. **Local cache** - Checks for a cached version match
+2. **go-versions repository** - Pulls from the main branch of the [go-versions repository](https://github.com/actions/go-versions/blob/main/versions-manifest.json)
+3. **Direct download** - Falls back to downloading directly from [go.dev](https://go.dev/dl)
+
+To change the default behavior, use the `check-latest` input.
+
+> **Note**: The setup-go action uses executable binaries built by the Golang team. The action does not build golang from source code.
+
+## Usage
+
+### Basic Setup
 
-## Basic:
 ```yaml
 steps:
-  - uses: actions/checkout@v2
-  - uses: actions/setup-go@v2
+  - uses: actions/checkout@v5
+  - uses: actions/setup-go@v6
     with:
-      go-version: '1.16.1' # The Go version to download (if necessary) and use.
+      go-version: '1.23'
   - run: go run hello.go
 ```
 
+### Version Specifications
 
-## Check latest version:  
-
-The `check-latest` flag defaults to `false`. Use the default or set `check-latest` to `false` if you prefer stability and if you want to ensure a specific Go version is always used.
-
-If `check-latest` is set to `true`, the action first checks if the cached version is the latest one. If the locally cached version is not the most up-to-date, a Go version will then be downloaded. Set `check-latest` to `true` if you want the most up-to-date Go version to always be used.
-
-> Setting `check-latest` to `true` has performance implications as downloading Go versions is slower than using cached versions.
+#### Semantic Versioning
 
 ```yaml
 steps:
-  - uses: actions/checkout@v2
-  - uses: actions/setup-go@v2
+  - uses: actions/checkout@v5
+  - uses: actions/setup-go@v6
     with:
-      go-version: '1.14'
+      go-version: '^1.23.1' # The Go version to download (if necessary) and use.
+  - run: go version
+```
+
+```yaml
+steps:
+  - uses: actions/checkout@v5
+  - uses: actions/setup-go@v6
+    with:
+      go-version: '>=1.22.0'
+  - run: go version
+```
+
+> **Important**: Due to YAML parsing behavior, always wrap version numbers in single quotes:
+> ```yaml
+> go-version: '1.22'  # Correct
+> go-version: 1.22    # Incorrect - YAML parser interprets as 1.2
+> ```
+
+#### Pre-release Versions
+
+```yaml
+# RC version
+steps:
+  - uses: actions/checkout@v5
+  - uses: actions/setup-go@v6
+    with:
+       go-version: '1.24.0-rc.1' # The Go version to download (if necessary) and use
+  - run: go version
+```
+
+```yaml
+# Beta version
+steps:
+  - uses: actions/checkout@v5
+  - uses: actions/setup-go@v6
+    with:
+      go-version: '1.23.0-beta.1' # The Go version to download (if necessary) and use
+  - run: go version
+```
+
+#### Version Aliases
+
+**Stable Release**
+
+If `stable` is provided, action will get the latest stable version from the [go-versions](https://github.com/actions/go-versions/blob/main/versions-manifest.json) repository manifest.
+```yaml
+steps:
+  - uses: actions/checkout@v5
+  - uses: actions/setup-go@v6
+    with:
+      go-version: 'stable' # Latest stable version
+  - run: go version
+```
+
+**Previous Stable Release**
+
+If `oldstable` is provided, when the current release is 1.23.x, the action will resolve version as 1.22.x, where x is the latest patch release.
+```yaml
+steps:
+  - uses: actions/checkout@v5
+  - uses: actions/setup-go@v6
+    with:
+      go-version: 'oldstable' # Previous stable version
+  - run: go version
+```
+
+> **Note**: Using aliases is equivalent to using the corresponding minor release with `check-latest: true`
+
+### go-version-file
+
+The action can automatically detect the Go version from various project files using the `go-version-file` input. This parameter supports `go.mod`, `go.work`, `.go-version`, and `.tool-versions` files.
+
+> **Note**: If both `go-version` and `go-version-file` are provided, `go-version` takes precedence.
+
+#### go.mod File
+
+Automatically detect the Go version from your project's `go.mod` file:
+
+```yaml
+steps:
+  - uses: actions/checkout@v5
+  - uses: actions/setup-go@v6
+    with:
+      go-version-file: 'go.mod'
+  - run: go version
+```
+
+**Version Resolution from go.mod:**
+1. Uses the `toolchain` directive version if present
+2. Falls back to the `go` directive version
+3. If no patch version is specified, uses the latest available patch
+
+#### go.work File
+
+Use the Go version specified in your `go.work` file:
+
+```yaml
+steps:
+  - uses: actions/checkout@v5
+  - uses: actions/setup-go@v6
+    with:
+      go-version-file: 'go.work'
+  - run: go version
+```
+
+#### .go-version File
+
+Read the Go version from a `.go-version` file:
+
+```yaml
+steps:
+  - uses: actions/checkout@v5
+  - uses: actions/setup-go@v6
+    with:
+      go-version-file: '.go-version'
+  - run: go version
+```
+
+#### .tool-versions File
+
+Use the Go version from an [`.tool-versions`](https://asdf-vm.com/manage/configuration.html#tool-versions) file:
+
+```yaml
+steps:
+  - uses: actions/checkout@v5
+  - uses: actions/setup-go@v6
+    with:
+      go-version-file: '.tool-versions'
+  - run: go version
+```
+
+#### Custom File Paths
+
+The action searches for version files relative to the repository root by default. You can specify a custom path:
+
+```yaml
+steps:
+  - uses: actions/checkout@v5
+  - uses: actions/setup-go@v6
+    with:
+      go-version-file: 'path/to/.go-version'
+  - run: go version
+```
+
+**Supported Version Formats:**
+- Major and minor only: `1.25` (action will use the latest patch version, e.g., `1.25.4`)
+- Major, minor, and patch: `1.25.4` (exact version)
+
+### Check Latest Version
+
+The check-latest flag defaults to false for stability. This ensures your workflow uses a specific, predictable Go version.
+When `check-latest: true`, the action verifies if your cached Go version is the latest available. If not, it downloads and uses the newest version.
+
+```yaml
+steps:
+  - uses: actions/checkout@v5
+  - uses: actions/setup-go@v6
+    with:
+      go-version: '1.23'
+      check-latest: true # Always check for the latest patch release
+  - run: go version
+```
+
+**Performance Considerations:**
+- `check-latest: false` (default) - Uses cached versions for faster builds
+- `check-latest: true` - Downloads the latest version, slower but ensures up-to-date releases
+
+### Caching
+
+The action features integrated caching for Go modules and build outputs. Built on [toolkit/cache](https://github.com/actions/toolkit/tree/main/packages/cache), it simplifies the caching process by requiring fewer configuration options. The cache input is optional, and caching is turned on by default.
+
+#### Automatic Caching
+
+Default behavior: Searches for `go.sum` in the repository root and uses its hash for the cache key.
+
+```yaml
+steps:
+  - uses: actions/checkout@v5
+  - uses: actions/setup-go@v6
+    with:
+      go-version: '1.23'
+      # cache: true (default)
+  - run: go run hello.go
+```
+
+#### Advanced Caching Scenarios
+
+For advanced scenarios, use `cache-dependency-path` to specify:
+- **Multiple dependency files**: When your project has dependencies in different directories
+- **Custom locations**: When your `go.sum` files are not in the repository root
+- **Monorepos**: When managing multiple Go modules in a single repository
+- **Glob patterns**: For flexible file matching
+
+```yaml
+# Example: Monorepo with multiple go.sum files
+steps:
+  - uses: actions/checkout@v5
+  - uses: actions/setup-go@v6
+    with:
+      go-version: '1.23'
       check-latest: true
+      cache-dependency-path: |
+        subdir/go.sum
+        tools/go.sum
   - run: go run hello.go
 ```
 
-## Matrix Testing:
+```yaml
+# Example: Using glob patterns to match all go.sum files
+steps:
+  - uses: actions/checkout@v5
+  - uses: actions/setup-go@v6
+    with:
+      go-version: '1.23'
+      cache-dependency-path: "**/*.sum"
+  - run: go run hello.go
+```
+
+#### Disable Caching
+
+```yaml
+steps:
+  - uses: actions/checkout@v5
+  - uses: actions/setup-go@v6
+    with:
+      go-version: '1.23'
+      cache: false
+  - run: go run hello.go
+```
+
+> **Note**: If caching fails, the action logs a warning but continues execution without interrupting your workflow.
+
+### Matrix Testing
+
+Test across multiple Go versions:
+
 ```yaml
 jobs:
-  build:
+  test:
     runs-on: ubuntu-latest
     strategy:
       matrix:
-        go: [ '1.14', '1.13' ]
-    name: Go ${{ matrix.go }} sample
+        go-version: ['1.21', '1.22', '1.23']
     steps:
-      - uses: actions/checkout@v2
-      - name: Setup go
-        uses: actions/setup-go@v2
+      - uses: actions/checkout@v5
+      - uses: actions/setup-go@v6
         with:
-          go-version: ${{ matrix.go }}
-      - run: go run hello.go
+          go-version: ${{ matrix.go-version }}
+      - run: go test ./...
 ```
 
-### Supported version syntax
+## Advanced Configuration
+
+### Supported Version Syntax

+## Using setup-go on GHES
+
+setup-go comes pre-installed on GHES when Actions is enabled. For dynamic Go version downloads, the action fetches distributions from the [go-versions repository](https://github.com/actions/go-versions/) on github.com (external to your appliance).
+
+These calls to `actions/go-versions` are made via unauthenticated requests, which are limited to 60 requests per hour per IP. If more requests are made within the time frame, then the action leverages the raw API to retrieve the version-manifest. This approach does not impose a rate limit and hence facilitates unrestricted consumption. This is particularly beneficial for GHES runners, which often share the same IP, to avoid the quick exhaustion of the unauthenticated rate limit. If that fails as well the action will try to download versions directly from [go.dev](https://go.dev/dl).
+
+If that fails as well you can get a higher rate limit with generating a personal access token on github.com and passing it as the token input to the action:
+
+```yaml
+uses: actions/setup-go@v6
+with:
+  token: ${{ secrets.GH_DOTCOM_TOKEN }}
+  go-version: '1.23'
+```
+
+### Offline Runners
+
+For runners without github.com access, Go versions must be pre-cached in the runner's tool cache. See "[Setting up the tool cache on self-hosted runners without internet access](https://docs.github.com/en/enterprise-server@3.2/admin/github-actions/managing-access-to-actions-from-githubcom/setting-up-the-tool-cache-on-self-hosted-runners-without-internet-access)".
+
+## Recommended Permissions
+
+When using the setup-go action in your GitHub Actions workflow, it is recommended to set the following permissions to ensure proper functionality:
+
+```yaml
+permissions:
+  contents: read # Required to checkout code and install dependencies
+```
