Despite what some may say, some level of documentation is needed in Agile. Agile is not an excuse to be a cowboy.
Having said that, not being a cowboy does not mean being wasteful. You don't install documents in production. Be sane. Document only what's needed for regulatory, GAAP or other purposes. If you need to document in case someone leaves, you don't have collective code ownership and aren't pairing properly.
