I hate this in documentation. Snippets of code or config that don't work on their own, and it may not even be clear where they're supposed to go or what they're nested in. May use imports the name of which cannot be found on the page. That kind of crap.
Please, at the very least, put a full-fat example or a link to it at the bottom of the page. Something.
The amount of “put this in your config file” for things they are part of build chains for JS without specifying where that file lives. Oh, the word “config” is a link to the configuration docs page but…that just lists the possible config options and not where they live.
