+Official container images for [Ray](https://github.com/ray-project/ray).
+These images contains working Python virtual environments and required
+dependencies to run launche Ray nodes and form Ray clusters.
+everything needed to get started with running Ray. One can use the images
+for local development, or launch clusters with [Ray VM launcher][vm-launcher],
+[KubeRay][kuberay], or running them on [Anyscale][anyscale].
+
+Source that builds the images are [here][source].

+## Tags
+
+Images are `tagged` with the format
+`{Ray version}[-{Python version}][-{Platform}][-{Architecture}]`.
+
+`Ray version` tag can be one of the following:
+
+| Ray version tag | Description |
+| --------------- | ----------- |
+| `latest`        | The most recent Ray release. |
+| `x.y.z`         | A specific Ray release version, e.g. 2.53.0 |
+| `nightly`       | The most recent Ray development build (a recent commit from GitHub `master`) |
+
+The optional `Python version` tag specifies the Python version in the image.
+All Python versions supported by Ray are available, e.g. `py310`, `py311`, and
+`py312`. If unspecified, the tag points to an image using `Python 3.10`.
+
+The optional `Platform` tag specifies the platform where the image is intended
+for:
+
+| Platform tag    | Description |
+| --------------- | ----------- |
+| `-cpu`          | Based off of an Ubuntu image. |
+| `-cuXX`         | Based off of an NVIDIA CUDA image with the specified CUDA version `xx`. They require the NVIDIA Docker Runtime. |
+| `-gpu`          | Aliases to a specific `-cuXX` tagged image. |
+| no tag          | Aliases to `-cpu` tagged images. |
+
+The optional `Architecture` tag can be used to specify images for different CPU
+architectures.  Currently, we support the `x86_64` (`amd64`) and `aarch64`
+(`arm64`) architectures.
+
+Please note that suffixes are only used to specify `aarch64` images.
+No suffix means that it is a multi-platform image index.
+
+| Platform tag | Description                 |
+|--------------|-----------------------------|
+| no tag       | Multi-platform image index. |
+| `-aarch64`   | arm64-compatible images     |
