I'm not sure how to implement this but I think it's important for the quality of our docs.

In Apache Lucene, if I mess up javadocs, "ant compile" or "ant pre-commit" will catch it.

But for ES, I think (?) I must clone the docs repo (https://github.com/elastic/docs) and follow its steps to make sure all is good.

Can we make this easier somehow, e.g. fold it under "mvn verify"?
