-########################################################################################################################
-# Introduction
-########################################################################################################################
-# This is a multi-stage build, which eventually results in a squashed image.
-# The image intended for release/use is the one obtained using `docker build --target=superchain ...`.
-#
-# Stages are as follows
-# 1. [bindist]    Prepare a bunch of binary distributions
-# 2. [staging]    Prepare the superchain staging image
-# 3. [superchain] Squash into a single layer
-# 4. [test]       Run tests on the superchain stage
-#
-# Multi-stage build allows several of these steps to run in parallel up to some point. It makes the build cache usage
-# more efficient, and allows us to run cross-architecture builds in the most efficient possible manner, by running the
-# "platform-independent" elements within the build platform, which does not require any kind of emulation.

-
-Any other tags should be *considered* deprecated or in the case of `nightly` images *experimental*.
-
-## Included Language SDKs

-## Building
-
-This docker image must be built from the package root with the Dockerfile set to
-`superchain/Dockerfile`:
-
-```console
-docker build . -f superchain/Dockerfile -t jsii/superchain:local
-```
-
-In case the tests fail, skip the tests and inspect the image manually:
-
-```console
-docker build . -f superchain/Dockerfile -t jsii/superchain:local --target=superchain
-```
-
-### NodeJS and NPM
-
-If you are building this image from source, you can control the Node version with the
-`NODE_MAJOR_VERSION` build argument:
-
-```console
-docker build [...] --build-arg NODE_MAJOR_VERSION=22
-```
-
-### Image tags
-
-Image tags are named using the following pattern:
-
-```text
-public.ecr.aws/jsii/superchain:<JSII-MAJOR>-<BASE>(-node<NODE-MAJOR>)(-nightly)
-```
-
-- `<JSII-MAJOR>` is the major line of the jsii toolchain (must be `1`)
-- `<BASE>` is the base image tag, currently supported base images are
-- `<NODE-MAJOR>` is the major version of Node.js contained in the image
-- `-nightly` images are released from the `HEAD` of the [`aws/jsii`][jsii]
-  repository and should typically not be used for production workloads
-
-## Support policy
-
-Generally only actively versions that are actively supported by upstream projects are maintained in superchain.
-
-### Debian
-
-We only publish images for Debian releases that receive updates from the [Debian security team]([debian-releases](https://wiki.debian.org/DebianReleases#Production_Releases)).
-All superchain images are based on the slim variant.
-
-### Node
-
-We publish images variants for Node versions that are Current or LTS.
-We include the npm version that ships with the version of Node.
-
-### Python
-
-The image includes the most recent Python version available for the respective Debian distribution.
-A complete list can be viewed on the [Debian website](https://wiki.debian.org/Python#Supported_Python_Versions).
-
