+### Buf Registry and Tags
+
+The IBC-Go protobuf definitions are published to the [Buf Schema Registry](https://buf.build/cosmos/ibc) on both the `main` branch and for all release tags. When a new tag is created, the protobuf definitions are automatically pushed to the Buf registry with appropriate commit labels that include the tag name. This allows consumers to depend on specific versions of the API.
+
+These tagged versions can be referenced in your `buf.yaml` files as dependencies, for example:
+
+```yaml
+deps:
+  - buf.build/cosmos/ibc:v7.2.0  # Specific version
+```
+
 ## Developing and testing
 
 - The latest state of development is on `main`.

+## Buf Schema Registry
+
+IBC-Go Protobuf definitions are hosted on the [Buf Schema Registry](https://buf.build/cosmos/ibc).
+
+The registry includes all IBC-Go Protobuf definitions and is updated:
+- When changes are made to Protobuf files on the `main` branch
+- When a new version of IBC-Go is released with a tag (e.g., `v7.3.0`)
+
+You can browse the Protobuf definitions directly on the Buf Schema Registry:
+- [Main branch](https://buf.build/cosmos/ibc/docs/main)
+- Tagged versions are available in the "Tags" section
+
+## Using Tagged Versions in Your Projects
+
+When depending on IBC-Go Protobuf definitions in your own projects, you can specify a particular tagged version to ensure API stability:
+
+```yaml
+# In your buf.yaml file
+deps:
+  - buf.build/cosmos/ibc:v7.3.0  # Replace with your desired version
+```
+
+This ensures your project always uses the same version of the API definitions, regardless of updates to the main branch.
+
+## Generated Documentation
