+# Test Runner Docker Container
+
+This repository provides a Dockerfile for building an ARM-based container
+with Ruby 3.2.2 and several testing gems. The container also installs
+Chromium so it can be used for headless browsing.
+
+## Building
+
+Build the image using Docker's buildx so the container is built for ARM64:
+
+```bash
+docker buildx build --platform linux/arm64 -t test-runner:arm64 .
+```
+
+The resulting image contains all gems listed in the `Gemfile` and can be
+used to execute tests or scripts that depend on them.
+
+## Running with Local Tests
+
+To execute tests stored on your machine, map the directory containing
+your test suite to `/app` inside the container. For example, if your
+tests are located in `~/lets-qa/acceptance/`, start the container with:
+
+```bash
+docker run -it --rm -v ~/lets-qa/acceptance:/app test-runner:arm64 bash
+```
+
+This command launches the container with the current working directory set
+to `/app`, where your tests are mounted. From there you can run any
+commands you need, such as `bundle exec cucumber` or `bundle exec rspec`.
