| # Additional notes: | |
| # - The workflow uses the github.repository context to name the image, ensuring it's tied to your repository | |
| # - The GITHUB_TOKEN is automatically provided by GitHub Actions, no need to set it up manually | |
| # - The Docker metadata action automatically generates appropriate tags based on the release version | |
| # - The Julia version can be easily updated by changing the JULIA_VERSION environment variable at the top of the workflow | |
