 # cmake-format
+
+## Quick Run
+
+```bash
+cd your/source/tree
+podman run --rm -v "${PWD}"/src ghcr.io/cwpearson/clang-format-16:latest clang-format ...
+```
+
+Inside the container, the working directory is /src, we use the volume mount to map the host working directory `${PWD}` into `/src`: `-v "${PWD}"/src`.
+
+## Building the Image Locally
+
+```bash
+podman build -f cmake-format-0.6.13.dockerfile -t cmake-format-0.6.13:latest
+podman run --rm -v "${PWD}"/src cmake-format-0.6.13:latest cmake-format ...
+```
+
+## Deploy
+
+1. Create a "personal access token (classic)" with `write:packages`
+  * account > settings > developer settings > personal access tokens
+2. Put that personal access token as the repository secret `GHCR_TOKEN`.
