 ## 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 `go` directive in `go.mod` 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.
 > The action will search for the `go.mod` file relative to the repository root
