-## Support for newer Ruby versions
-
-GitHub Actions is set up to gather the latest available Ruby versions with the [ruby-versions-action](https://github.com/moritzheiber/ruby-versions-action) and feed it to the build process. The plan is to run the build pipeline and update the REAMDE from a template regularly (e.g. weekly) in the future. For now this has to be done manually, so feel free to open a new issue once a new release needs to be supported (it usually takes a few minutes to trigger the pipeline and update the README).
-
-## Compiling your own image
-
-The `Dockerfile` is set up in a way which makes it possible to compile pretty much any recent Ruby release [from the index on the ruby-lang.org website](https://cache.ruby-lang.org/pub/ruby/index.txt). The only two build arguments you need to provide are `RUBY_VERSION` (e.g. `3.1.2`) and the associated `sha256` checksum as `RUBY_CHECKSUM` (e.g. `ca10d017f8a1b6d247556622c841fc56b90c03b1803f87198da1e4fd3ec3bf2a`) of the `tar.gz` package associated with the relevant version.
-
-You can always use the [ruby-version-checker](https://github.com/moritzheiber/ruby-version-checker-rs) container to fetch the latest available Ruby releases and their corresponding checksums:
-
-```console
-$ docker run ghcr.io/moritzheiber/ruby-version-checker
-# [...]
-[
-  {
-    "name": "3.0.6",
-    "url": "https://cache.ruby-lang.org/pub/ruby/3.0/ruby-3.0.6.tar.gz",
-    "sha256": "6e6cbd490030d7910c0ff20edefab4294dfcd1046f0f8f47f78b597987ac683e"
-  },
-  {
-    "name": "3.1.4",
-    "url": "https://cache.ruby-lang.org/pub/ruby/3.1/ruby-3.1.4.tar.gz",
-    "sha256": "a3d55879a0dfab1d7141fdf10d22a07dbf8e5cdc4415da1bde06127d5cc3c7b6"
-  },
-  {
-    "name": "3.2.2",
-    "url": "https://cache.ruby-lang.org/pub/ruby/3.2/ruby-3.2.2.tar.gz",
-    "sha256": "96c57558871a6748de5bc9f274e93f4b5aad06cd8f37befa0e8d94e7b8a423bc"
-  }
-]
-```
-
-
-If you wish to pass additional compile-time options you can use the build argument `ADDITIONAL_FLAGS` (e.g. to enable YJIT support for Ruby >= `3.2.x`):
-
-```console
-$ docker build \
-  --build-arg RUBY_VERSION="3.1.4" \
-  --build-arg RUBY_CHECKSUM="a3d55879a0dfab1d7141fdf10d22a07dbf8e5cdc4415da1bde06127d5cc3c7b6" \
-  --build-arg ADDITIONAL_FLAGS="--enable-yjit" \
-  -t ruby-jemalloc:3.1.4-slim .
-```
-The `Dockerfile` uses [the official Ruby `slim` image](https://hub.docker.com/_/ruby) by default, but you can also use your own base image by passing the build argument `IMAGE_NAME`:
-
-```console
-$ docker build \
-  --build-arg RUBY_VERSION=3.1.4 \
-  --build-arg RUBY_CHECKSUM=a3d55879a0dfab1d7141fdf10d22a07dbf8e5cdc4415da1bde06127d5cc3c7b6 \
-  --build-arg IMAGE_NAME=ubuntu:22.04 \
-  -t ruby-jemalloc:3.1.4-ubuntu-22.04 .
-```
-_Note: Ruby `3.4.1-slim` is the default when building the Docker image without any build arguments._
