Updating npm packages

[andrecasal]

I update my npm packages this way. Do you guys follow the same practice?

If so, should we add npm-check-updates to package.json?

[kentcdodds]

I do the same thing. I'd rather have this as part of the docs. Would you be willing to make a docs page about this?

[andrecasal]

Sure 👍
