+WinGet manifests for the Codex CLI
+
+Local testing
+
+- Validate: `winget validate .\manifests\o\OpenAI\Codex\0.57.0`
+- Install from local manifests: `winget install --manifest .\manifests\o\OpenAI\Codex\0.57.0`
+- Verify: `codex --version` and `where codex`
+- Uninstall: `winget uninstall OpenAI.Codex`
+
+Submitting to winget-pkgs
+
+- Ensure URLs and SHA256 match the public GitHub Release for this version.
+- Submit with `wingetcreate submit <path>` or copy this tree into a fork of `microsoft/winget-pkgs` under the same path.
+Winget manifests
+
+- Templates live under `.github/winget_templates/` and use placeholders:
+  - `{{VERSION}}`, `{{X64_SHA256}}`, `{{ARM64_SHA256}}`
+- The CI calls a composite action (`.github/actions/winget-submit`) from the release job:
+  - Fills the templates using the release version and precomputed SHA256s,
+  - Validates the manifests with `winget validate` (submission is separate).
+
+Setup
+
+- Ensure releases include raw Windows assets:
+  - `codex-x86_64-pc-windows-msvc.exe`
+  - `codex-aarch64-pc-windows-msvc.exe`
+- Add a repo secret `WINGET_PUBLISH_PAT` with `repo` (or `public_repo`) scope for PR submission.
+
+Local test
+
+- Build a versioned manifest set:
+  - Replace placeholders in the files under `template/` and stage under `manifests/o/OpenAI/Codex/<VERSION>/`.
+- Validate:
+  - `wingetcreate validate manifests/o/OpenAI/Codex/<VERSION>`
+- Install locally:
+  - `winget install --manifest manifests/o/OpenAI/Codex/<VERSION>`
