FAQ on Branding

Is it "npm" or "NPM" or "Npm"?

npm should never be capitalized unless it is being displayed in a location that is customarily all-capitals (ex. titles on man pages).

Is "npm" an acronym for "Node Package Manager"?

Contrary to popular belief, npm is not an acronym for "Node Package Manager." It is a recursive backronymic abbreviation for "npm is not an acronym" (if the project were named "ninaa," then it would be an acronym). The precursor to npm was actually a bash utility named "pm", which was the shortform name of "pkgmakeinst" - a bash function that installed various things on various platforms. If npm were ever considered an acronym, it would be as "node pm" or, potentially, "new pm".
