Hi @Medemt,
Yes, our website and documentation get updated regularly to reflect updated information, and things like improved examples. There’s an overview of our various resources here.
For ardusub.com specifically, that’s (currently) generated from our ardusub-gitbook repository. We don’t include explicit “last updated” dates on the pages, but if you’re interested you can see what updates have been made from the commits, and you can see things that need to be/are planned to be updated in the issues. Note that some commits and issues refer to structural changes of how the website gets generated, rather than just content updates.
We’re also in the process of changing our documentation building system and structure - the new docs are generated by our ardusub-zola repository, and we’ll be moving our existing docs and making new docs there quite soon. That’s currently hosted at Docs | ArduSub, and will be moved over to ardusub.com once the old content has been transferred.
