 previously reported no problems may now do so).

+### Usage with Buf
+
+[Buf][] builds tooling to make schema-driven, Protobuf-based API development
+reliable and user-friendly for service producers and consumers.
+This includes the `buf lint` command, which can be used to lint Protobuf files.
+The API linter can be used as a plugin for `buf lint`.
+
+To install the plugin, run:
+
+```sh
+go install github.com/aep-dev/api-linter/cmd/buf-plugin-aep@latest
+```
+
+It will install `buf-plugin-aep` into your local Go binary directory
+`$HOME/go/bin`. Ensure that your operating system's `PATH` contains the Go
+binary directory.
+
+Then, integrate the following into your `buf.yaml` file:
+
+```yaml
+lint:
+  use:
+    - AEP
+plugins:
+  - plugin: buf-plugin-aep
+```
+
+Now, you can run `buf lint` to lint your Protobuf files against the AEP rules.
+
+An example of building and linting with Buf can be found in the
+[example](./example) directory.
+
+More information on using Buf to lint Protobuf files can be found in the
+[Buf lint documentation][].
