+
+**[Runtime Node](https://github.com/Runtimes-Node/Runtime-Node)** is an open-source, production-grade Docker base image tailored for executing [Node.js](https://github.com/topics/nodejs) applications with maximum security and minimal overhead. Managed under the **[Runtimes-Node](https://github.com/Runtimes-Node)** organization, it provides developers with a strictly distroless runtime environment for their containerized workloads.
+
+Unlike traditional Node.js base images built on Debian or Alpine Linux, Runtime Node is assembled entirely `FROM scratch`. It completely eliminates the operating system layer, shells (like `bash` or `sh`), package managers (`apt` or `apk`), and all system utilities. It achieves this by extracting only the hand-picked binaries and shared libraries strictly required by the Node.js runtime.
+
+### Key Characteristics
+
+* **Zero-Bloat Footprint:** By shipping only what Node.js needs, the image size is radically reduced to approximately ~45 MB compressed.
+* **Hardened Security:** Removing the OS and shell results in zero known vulnerabilities and drastically shrinks the attack surface. 
+* **Production Ready Defaults:** The image is pre-configured with `NODE_ENV=production` and `TZ=UTC`, and includes essential routing like CA Certificates, `nsswitch.conf`, and IANA tzdata.
+* **Multi-Platform Architecture:** Natively supports both `linux/amd64` and `linux/arm64` deployments.
+
+By enforcing a strict distroless guarantee, the [Runtime-Node repository](https://github.com/Runtimes-Node/Runtime-Node) and its corresponding **[Docker Hub image](https://hub.docker.com/r/runtimenode/runtime-node)** allow developers to ship code securely, knowing there are no unnecessary tools for attackers to exploit.
