+## Package management
+
+The ability to easily install and manage dependencies and development tools is a
+key part of the user experience, and for that reason Node.js must provide a
+package manager as part of its distribution. Node.js includes `npm` for this
+purpose. This is for historical reasons — when `npm` was added in 2011, it was
+the only JavaScript package manager — and because it is the reference
+implementation for the npm registry, which is the de facto primary source for
+most JavaScript software. In accordance with our [policy][distribution-policy]
+of not including multiple dependencies or tools that serve the same purpose, the
+Node.js project does not include any other package managers.
