-### Go environment outputs
-
-Once Go is on the `PATH`, the action exposes the most commonly needed `go env` variables as outputs, so workflows don't have to query them in duplicated `bash`/`pwsh` steps — one expression works on Linux, macOS, and Windows. The values are a snapshot from setup time: anything a later step changes, such as setting `GOOS`/`GOARCH` to cross-compile, is not reflected.
-
-| Output | Notes |
-| --- | --- |
-| `GOPATH` | Go workspace root; `bin` and `pkg/mod` live under it |
-| `GOBIN` | Go 1.27+ reports an implicit `$GOPATH/bin` default; earlier releases are empty unless `GOBIN` is set |
-| `go-bin-path` | Uses `GOBIN`, or falls back to `bin` under the first `GOPATH` entry when `GOBIN` is empty. It normally matches `GOBIN` on Go 1.27+; the fallback is a convenience for earlier releases. When `GOBIN` is not explicitly set (in the environment or via `go env -w`), cross-compiled binaries go one level deeper, in `$GOPATH/bin/${GOOS}_${GOARCH}` |
-| `GOROOT` | Installation directory of the Go toolchain in use |
-| `GOCACHE` | Build cache directory |
-| `GOMODCACHE` | Module cache directory |
-| `GOOS` | Go notation (`linux`, `darwin`, `windows`), unlike `runner.os` |
-| `GOARCH` | Go notation (`amd64`, `arm64`), unlike `runner.arch` or the `x64` in the action's cache key |
-| `GOTOOLDIR` | Holds `compile`, `link`, `vet` and the other toolchain binaries |

-
-Quote `go-bin-path` in shell commands, since it may contain spaces. Variables without a dedicated output are not exposed; run `go env <NAME>` in a step when you need one.
-
-> [!NOTE]
-> These outputs need Go 1.9 or newer (`go env -json`); on older releases the action logs a message, leaves them unset and does not fail. `GOCACHE` needs Go 1.10 and `GOMODCACHE` needs Go 1.15.
-
 ## Custom download URL

 The `go-download-base-url` input lets you download Go from a mirror or alternative source instead of the default `https://go.dev/dl`. This can also be set via the `GO_DOWNLOAD_BASE_URL` environment variable; the input takes precedence over the environment variable.

 When a custom base URL is provided, the action skips the `actions/go-versions` manifest lookup and downloads directly from the specified URL.

-> **Note:** When constructing direct-download filenames, the original version string is preserved; native Go version normalization is used only for matching and tool cache lookups.
