+[Semgrep](https://semgrep.dev/) is a static analysis tool designed to scan code
+for security vulnerabilities and code quality issues.
+
+## Configuration
+
+Semgrep uses a YAML style configuration file. By default we will automatically
+use the following files if any are set in the root directory of your
+repostitory.
+
+- `semgrep.yml` or `semgrep.yaml`
+- `semgrep.config.yml` or `semgrep.config.yaml`
+
+Semgrep supports the following config files:
+
+- User-defined config file set at `reviews.tools.semgrep.config_file` in your
+  project's `.coderabbit.yaml` file or setting the "Review → Tools → Semgrep →
+  Config File" field in CodeRabbit's settings page.
+
+> Due to licensing CodeRabbit does not ship with the
+> [community-created Semgrep rules](https://github.com/returntocorp/semgrep-rules),
+> but you're free to use these in your own `semgrep.yml` config file.
+
+> **NOTE: CodeRabbit will only run Semgrep if your repository contains a Semgrep
+> config file. This config must use the default file names or you must define
+> the path to this file in the `.coderabbit.yaml` or config UI.**
