+# better-setup-node
+
+Fork of the setup-node recipe for git.madapes.com runners. The runner images are musl-based,
+so the official (glibc) Node builds fail with `no such file or directory` on exec — this
+installs the pinned musl build from the official unofficial-builds mirror. When
+`pnpm-version` is set, corepack (bundled with Node) activates that exact pnpm.
+
+```yaml
+- uses: https://git.madapes.com/actions/better-setup-node@v1
+  with: { node-version: "22.14.0", pnpm-version: "10.33.0" }
