+## Purpose
+
+- `import-boss` enforces import restrictions against all pull requests submitted to the [k/k](https://github.com/kubernetes/kubernetes) repository. There are a number of `.import-restrictions` files that in the [k/k](https://github.com/kubernetes/kubernetes) repository, all of which are defined in `YAML` (or `JSON`) format.
+
+## How does it work?
+
+- When a directory is verified, `import-boss` looks for a file called `.import-restrictions`. If this file is not found, `import-boss` will go up to the parent directory until it finds this `.import-restrictions` file.
+
+- Adding `.import-restrictions` files does not add them to CI runs. They need to be explicitly added to `hack/verify-import-boss.sh`. Once an `.import-restrictions` file is added, all of the sub-packages of this file's directory are added as well.
+
+### What are Rules?
+
+- If an `.import-restrictions` file is found, then all imports of the package are checked against each `rule` in the file. A `rule` consists of three parts:
+  - A `SelectorRegexp`, to select the import paths that the rule applies to.
+  - A list of `AllowedPrefixes`
+  - A list of `ForbiddenPrefixes`
+
+- An import is allowed if it matches at least one allowed prefix and does not match any forbidden prefixes. An example `.import-restrictions` file looks like this:
+
+```json
+{
+  "Rules": [
+    {
+      "SelectorRegexp": "k8s[.]io",
+      "AllowedPrefixes": [
+        "k8s.io/gengo/examples",
+        "k8s.io/kubernetes/third_party"
+      ],
+      "ForbiddenPrefixes": [
+        "k8s.io/kubernetes/pkg/third_party/deprecated"
+      ]
+    },
+    {
+      "SelectorRegexp": "^unsafe$",
+      "AllowedPrefixes": [
+      ],
+      "ForbiddenPrefixes": [
+        ""
+      ]
+    }
+  ]
+}
+```
+- Take note of `"SelectorRegexp": "k8s[.]io"` in the first block. This specifies that we are applying these rules to the `"k8s.io"` import path.
+- The second block explicitly matches the "unsafe" package, and forbids it ("" is a prefix of everything).
+
+### What are Inverse Rules?
+
+- In contrast to non-inverse rules, which are defined in importing packages, inverse rules are defined in imported packages.
+
+- Inverse rules allow for fine-grained import restrictions for "private packages" where we don't want to spread use inside of [kubernetes/kubernetes](https://github.com/kubernetes/kubernetes).
+
+- If an `.import-restrictions` file is found, then all imports of the package are checked against each `inverse rule` in the file. This check will continue, climbing up the directory tree, until a match is found and accepted.
+
+- Inverse rules also have a boolean `transitive` option. When this option is true, the import rule is also applied to `transitive` imports.
+  - `transitive` imports are dependencies not directly depended on by the code, but are needed to run the application. Use this option if you want to apply restrictions to those indirect dependencies.
+
+```yaml
+rules:
+  - selectorRegexp: k8s[.]io
+    allowedPrefixes:
+      - k8s.io/gengo/examples
+      - k8s.io/kubernetes/third_party
+    forbiddenPrefixes:
+      - k8s.io/kubernetes/pkg/third_party/deprecated
+  - selectorRegexp: ^unsafe$
+    forbiddenPrefixes:
+      - ""
+inverseRules:
+  - selectorRegexp: k8s[.]io
+    allowedPrefixes:
+      - k8s.io/same-repo
+      - k8s.io/kubernetes/pkg/legacy
+    forbiddenPrefixes:
+      - k8s.io/kubernetes/pkg/legacy/subpkg
+  - selectorRegexp: k8s[.]io
+    transitive: true
+    forbiddenPrefixes:
+      - k8s.io/kubernetes/cmd/kubelet
+      - k8s.io/kubernetes/cmd/kubectl
+```
+
+## How do I run import-boss within the k/k repo?
+
+- In order to include _test.go files, make sure to pass in the `include-test-files` flag:
+  ```sh
+  hack/verify-import-boss.sh --include-test-files=true
+  ```
+
+- To include other directories, pass in a directory or directories using the `input-dirs` flag:
+  ```sh
+  hack/verify-import-boss.sh --input-dirs="k8s.io/kubernetes/test/e2e/framework/..."
+  ```
