+# better-setup-go
+
+Fork of the setup-go recipe for git.madapes.com runners: installs the **pinned** Go from the
+official static tarball. No versions-manifest round-trip, no glibc runtime requirement —
+works on musl runner images where nothing needs installing first.
+
+```yaml
+- uses: https://git.madapes.com/actions/better-setup-go@v1
+  with: { go-version: "1.27.0" }
