Automatically check the documentation for broken links, broken assets, spelling mistakes, and grammatical issues.

A substantial amount of time is spent checking for spelling and mistakes when writing documentation. Once the docs are written, links and assets need to be tested to make sure they're not broken. While the sidebar navigation in VuePress handles broken-links very well, the body content of the docs doesn't have any process to check links.

These three things are automatable. The grammar checker will likely require a substantial amount of work; however since there doesn't seem to be any decent automation too already to deal with that.
