+This method defines the interception rules for matching against requests for a MockPool or MockPool. We can intercept multiple times on a single instance, but each intercept is only used once. 
+For example if you expect to make 2 requests inside a test, you need to call `intercept()` twice. Assuming you use `disableNetConnect()` you will get `MockNotMatchedError` on the second request when you only call `intercept()` once.
 
 When defining interception rules, all the rules must pass for a request to be intercepted. If a request is not intercepted, a real request will be attempted.

+# undici-types
+
+This package is a dual-publish of the [undici](https://www.npmjs.com/package/undici) library types. The `undici` package **still contains types**. This package is for users who _only_ need undici types (such as for `@types/node`). It is published alongside every release of `undici`, so you can always use the same version.
