+# WithRequired type
+
+This package defines the TypeScript utility type `WithRequired`. It transforms a type that has one or more optional fields into a type where those fields are required.
+
+For example:
+
+```
+import { WithRequired } from '@apollo/utils.withrequired';
+
+interface HasSomeOptionals {
+    foo: number;
+    bar?: string;
+    baz?: boolean;
+    quux?: string;
+}
+
+type MoreRequired = WithRequired<HasSomeOptions, 'bar' | 'baz'>;
+```
+
+The `MoreRequired` type is like `HasSomeOptionals`, but `bar` and `baz` are now required rather than optional. `quux` remains optional.
