This simple container should help you with building documentation when contributing to Sylius.
Docker... duh?
When you are in Sylius\docs
directory, just run:
# Linux
$ docker run --rm -v $(pwd):/app ghcr.io/arti0090/syliusdocbuilder
# Windows (powershell)
$ docker run --rm -v ${pwd}:/app ghcr.io/arti0090/syliusdocbuilder
and it will create /build
folder with html files which you can browse in your favourite browser.
