+## How to build
+
+```sh
+$ make ARCH=<amd64 | aarch64> NO_CODESIGN=1 pkginstaller
+
+# or to create signed pkg
+$ make ARCH=<amd64 | aarch64> CODESIGN_IDENTITY=<ID> PRODUCTSIGN_IDENTITY=<ID> pkginstaller
+```
+
+The generated pkg will be written to `out/podman-macos-installer-*.pkg`.
+Currently the pkg installs `podman`, `qemu`, `gvproxy` and `podman-mac-helper` to `/Applications/podman`
+
+The `qemu` build it uses is from [containers/podman-machine-qemu](https://github.com/containers/podman-machine-qemu)
+
+## Uninstalling
+
+```sh
+$ sudo rm -rf /opt/podman
+```
