-For packages with a small number of exports, we recommend explicitly listing
-each exports subpath entry. But for packages that have large numbers of
-subpaths, this might cause `package.json` bloat and maintenance issues.
+In addition to the [`"exports"`][] field, it is possible to define internal
+package import maps that only apply to import specifiers from within the package
+itself.
+
+Entries in the imports field must always start with `#` to ensure they are
+disambiguated from package specifiers.
+
+For example, the imports field can be used to gain the benefits of conditional
+exports for internal modules:
+
+```json
+// package.json
+{
+  "imports": {
+    "#dep": {
+      "node": "dep-node-native",
+      "default": "./dep-polyfill.js"
+    }
+  },
+  "dependencies": {
+    "dep-node-native": "^1.0.0"
+  }
+}
+```
+
+where `import '#dep'` does not get the resolution of the external package
+`dep-node-native` (including its exports in turn), and instead gets the local
+file `./dep-polyfill.js` relative to the package in other environments.
+
+Unlike the `"exports"` field, the `"imports"` field permits mapping to external
+packages.

+The resolution rules for the imports field are otherwise
+analogous to the exports field.
