+### 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** in fact an acronym for "Node Package Manager"; It is a recursive bacronymic abbreviation for **"npm is not an acronym"** (if the project was 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 to ever have been considered an acronym, it would be as "node pm" or, potentially "new pm".
