Thanks for the PR @rbrtmrtn I'll let our native English speakers confirm that this fix is correct (ping @mdo or @patrickhlauke) :)
However, if we merge it, the exact same modifications should be applied to parcel.md and webpack.md for consistency; they use the same sentences.

Looks correct to me. @rbrtmrtn Can you update the other guides too?

FYI, I applied the same modifications to the Parcel and Webpack guides via bd5cf86.
