+## Docker container
+
+### Prerequisites
+
+Before running the Docker container locally you must install Docker. See the [installation instructions].
+
+When building your production site in a [CI/CD] workflow, whether you can run the Docker container depends on the service provider. For example, GitHub Pages and GitLab Pages allow you to run the Docker container.
+
+To prevent ownership and permission problems, create the Hugo [cache directory](#cache-directory) and ignore the error if the directory already exists:
+
+```text
+mkdir -p $HOME/.cache/hugo_cache
+```
+
+[ci/cd]: https://en.wikipedia.org/wiki/CI/CD
+[installation instructions]: https://wiki.freebsd.org/Docker
+
+### Commands
+
+To build your site using the latest version:
+
+{{< code copy=true >}}
+docker run --rm -v .:/project -v $HOME/.cache/hugo_cache:/cache -p 1313:1313 ghcr.io/gohugoio/hugo:latest build
+{{< /code >}}
+
+To build your site and start the embedded web server using the latest version:
+
+{{< code copy=true >}}
+docker run --rm -v .:/project -v $HOME/.cache/hugo_cache:/cache -p 1313:1313 ghcr.io/gohugoio/hugo:latest server --bind="0.0.0.0"
+{{< /code >}}
+
+To use a specific version, in the commands above replace `latest` with any of the [tagged image versions]. For example, to build your site using v0.136.1:
+
+{{< code copy=true >}}
+docker run --rm -v .:/project -v $HOME/.cache/hugo_cache:/cache -p 1313:1313 ghcr.io/gohugoio/hugo:v0.136.1 build
+{{< /code >}}
+
+[tagged image versions]: https://github.com/gohugoio/hugo/pkgs/container/hugo/versions?filters%5Bversion_type%5D=tagged
+
+### Cache directory
+
+Attaching the host's Hugo cache directory to the container can significantly enhance performance, particularly for large and image-heavy sites. This allows Hugo to reuse previously generated content, reducing the need for repeated processing and transpilation.
+
+If you are using a custom Hugo cache directory, in the commands above replace `$HOME/.cache/hugo_cache` with the absolute path to your cache directory.
