 If you're adding a new page or making major changes to the documentation, such as adding new images, sections, or styling, we recommend that you work in a local copy of the repository and test the rendered HTML before submitting a PR. 
 
+#### Setting up a Docker-based copy of the repository
+
+If you have Docker installed, you can use Docker to test any major changes to the documentation website locally by using the following steps:
+
+1. [Fork this repository](https://docs.github.com/en/get-started/quickstart/fork-a-repo) and clone your fork in the directory of your choice.

+> 1. Change the `url` setting in `_config_docker.yml` to your URL: `url: "http://10.0.0.5:4000"`
+> 1. Change the `HOST` and `JEKYLL_ENV` variables: `docker run -p 4000:4000 -e JEKYLL_ENV=production -e HOST=0.0.0.0 -v $(pwd):/app documentation-website
