 * version-specific documentation, where a new release of the Kroxylicious software produces new documentation about that version.
 
 The version-specific content has index pages enumerating the downloads and documentation publications, which is templated using liquid templates.

+When you make a change you should test it. 
+The script `./run.sh` can be used to serve the site from a docker container. 
+The preview site can then be accessed at `http://127.0.0.1:4000/`.
+
+This GitHub repository is hosted on GitHub at `https://github.com/kroxylicious/kroxylicious.github.io`.
+You can use the `gh` tool to interact with GitHub PRs.
+Note that we do not use the website repo for issues. 
+Instead, issues for the website are held in the main Kroxylicious repo `https://github.com/kroxylicious/kroxylicious`.
+So if you need to interact with website issues you can use the `-R kroxylicious/kroxylicious` option, for example: `gh issue list -R kroxylicious/kroxylicious`.
