-If you navigate to the front page of the STACK documentation _on your server_ then you can find the version number of the STACK plugin at the bottom of the page.  If your site is `https://maths.assessment/site` then the URL of the STACK documentation is probably `https://maths.assessment/site/question/type/stack/doc/doc.php`.  We distribute the documentation with the source code so you can check the STACK features you have available on your site by referring to this version of the documentation (rather than the docs on [https://docs.stack-assessment.org/](https://docs.stack-assessment.org/) which documents the latest release.).
