 ## Getting go version from the go.mod file
 
-The `go-version-file` input accepts a path to a `go.mod` file or a `go.work`
-file that contains the version of Go to be used by a project. The version taken
-from thils file will be:
-
-  - The version from the `toolchain` directive, if there is one, otherwise
-  - The version from the `go` directive
-
-The version can specify a patch version or omit it altogether (e.g., `go 1.22.0` or `go 1.22`).
-
-If a patch version is specified, that specific patch version will be used.  
-If no patch version is specified, it will search for the latest available patch version in the cache,
-[versions-manifest.json](https://github.com/actions/go-versions/blob/main/versions-manifest.json), and the
-[official Go language website](https://golang.org/dl/?mode=json&include=all), in that order.
+The `go-version-file` input accepts a path to a `go.mod` file or a `go.work` file that contains the version of Go to be
+used by a project. As the `go.mod` file contains only major and minor (e.g. 1.18) tags, the action will search for the
+latest available patch version sequentially in the runner's directory with the cached tools, in
+the [versions-manifest.json](https://github.com/actions/go-versions/blob/main/versions-manifest.json) file or at the go
+servers.
 
 If both the `go-version` and the `go-version-file` inputs are provided then the `go-version` input is used.

+distributions, `setup-go` downloads distributions from [`actions/go-versions`](https://github.com/actions/go-versions)
+on github.com (outside of the appliance). These calls to `actions/go-versions` are made via unauthenticated requests,

+like: `##[error]API rate limit exceeded for...`. After that error the action will try to download versions directly
+from https://storage.googleapis.com/golang, but it also can have rate limit so it's better to put token.
 
-These calls to `actions/go-versions` are made via unauthenticated requests, which are limited to [60 requests per hour per IP](https://docs.github.com/en/rest/overview/resources-in-the-rest-api#rate-limiting).
-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 https://storage.googleapis.com/golang.
-
-If that fails as well you can get a higher rate limit with [generating a personal access token on github.com](https://github.com/settings/tokens/new) and passing it as the `token` input to the action:
+To get a higher rate limit, you
+can [generate a personal access token on github.com](https://github.com/settings/tokens/new) and pass it as the `token`
+input for the action:
 
 ```yaml
-uses: actions/setup-go@v6
+uses: actions/setup-go@v4
 with:
   token: ${{ secrets.GH_DOTCOM_TOKEN }}
   go-version: '1.18'
 ```
 
-If the runner is not able to access github.com, any Go versions requested during a workflow run must come from the runner's tool cache.
+If the runner is not able to access github.com, any Go versions requested during a workflow run must come from 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)"
 for more information.
 
-## 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 # access to check out code and install dependencies
-```
