 ## Using Docker Image
 
-You can also use [docker image](https://hub.docker.com/r/jqtype/rpxy) instead of directly executing the binary. There are only several docker-specific environment variables.
+You can also use `docker` image hosted on [Docker Hub](https://hub.docker.com/r/jqtype/rpxy) and [GitHub Container Registry](https://github.com/junkurihara/rust-rpxy/pkgs/container/rust-rpxy) instead of directly executing the binary. See [`./docker/README.md`](./docker/README.md) for the differences on image tags.

+There are only several docker-specific environment variables.
 
 - `HOST_USER` (default: `user`): User name executing `rpxy` inside the container.
 - `HOST_UID` (default: `900`): `UID` of `HOST_USER`.

+# Docker Images of `rpxy`
+
+The `rpxy` docker images are hosted both on [Docker Hub](https://hub.docker.com/r/jqtype/rpxy) and [GitHub Container Registry](https://github.com/junkurihara/rust-rpxy/pkgs/container/rust-rpxy). Differences among tags are summarized as follows.
+
+## Latest Builds
+
+- `latest`: Built from the `main` branch with default features, running on Ubuntu.
+- `latest-slim`, `slim`: Built by `musl` from the `main` branch with default features, running on Alpine.
+- `latest-s2n`, `s2n`: Built from the `main` branch with the `http3-s2n` feature, running on Ubuntu.
+
+## Nightly Builds
+
+- `nightly`: Built from the `develop` branch with default features, running on Ubuntu.
+- `nightly-slim`: Built by `musl` from the `develop` branch with default features, running on Alpine.
+- `nightly-s2n`: Built from the `develop` branch with the `http3-s2n` feature, running on Ubuntu.
+
+## Caveats
+
+Due to some compile errors of `s2n-quic` subpackages with `musl`, `nightly-s2n-slim` or `latest-s2n-slim` are not yet provided.
