+## Using Buf
+
+marshal-zap [Buf](https://buf.build/) repository is here.
+
+https://buf.build/kei2100/protoc-gen-marshal-zap
+
+So, you can `buf generate` by setting up the following in your project.
+
+```yaml
+# buf.yaml
+version: v1
+deps:
+  - buf.build/kei2100/protoc-gen-marshal-zap
+breaking:
+  use:
+    - FILE
+lint:
+  use:
+    - DEFAULT
+```
+
+```yaml
+# buf.gen.yaml
+version: v1
+plugins:
+  - plugin: buf.build/protocolbuffers/go:v1.28.1
+    out: gen/go
+    opt: paths=source_relative
+  - plugin: marshal-zap
+    out: gen/go
+    opt: paths=source_relative
+```
+
 ## Development
 Compile marshal-zap.proto
