+# Ruby 3.4 packaged by Sourcemation
+
+An open source purely object-oriented programming language with a focus on
+simplicity and readability. Ruby 3.4 introduces performance improvements, YJIT
+optimizations, and modernized language features.
+
+This Ruby distribution is built from official source distributions by the
+Sourcemation automation team. It is based on the `sourcemation/debian-13-slim`
+base image, providing a highly optimized, clean, and secure environment.
+
+## Usage
+
+Run a temporary container with the Ruby REPL (`irb`) (don't forget the
+`-it` argument).
+
+```bash
+docker run --rm -it sourcemation/ruby-3.4:latest
+```
+
+### Advanced usage examples
+
+Example: create a Gemfile for a Ruby project, in your current directory:
+
+```bash
+docker run --rm -v "${PWD}:/your-project" -w "/your-project" sourcemation/ruby-3.4:latest bundle init
+```
+
+## Environment Vars, Ports, Volumes
+
+This image uses the following environment variables:
+
+```
+PATH="/usr/local/bundle/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin"
+GEM_HOME="/usr/local/bundle"
+BUNDLE_APP_CONFIG="/usr/local/bundle"
+APP_VERSION="3.4.10"
+APP_NAME="ruby-3.4"
+```
+
+This image exposes no ports by default.
+
+Please note that the ports need to be either manually forwarded with the
+`-p` option or let Docker choose some for you with the `-P` option.
+
+## Contributing and Issues
+
+We welcome your contributions! If you have new feature requests, want to report
+a bug, or wish to submit a pull request with your code or an image request, you
+can do so via the Sourcemation GitHub repository for this image.
