+description: CodeRabbit's guide to Buf.
+---
+
+[Buf](https://buf.build/) offers linting for Protobuf files.
+
+## Files
+
+Buf will run on files with the following extensions:
+
+- `.proto`
+
+## Configuration
+
+Buf uses a YAML style configuration file. We look for the following file anywhere in the repository:
+
+- `buf.yaml`
+
+If no config file is found, CodeRabbit will consider the following categories of strictness based on the profile selected:
+
+### Chill
+
+- `MINIMAL`
+
+### Assertive
+
+- `BASIC`
+
