 A `CODEOWNERS` file defines who owns specific files or paths in a repository. When you run `bin/codeownership validate`, a `.github/CODEOWNERS` file will automatically be generated and updated.
 
-If the `CODEOWNERS_PATH` environment variable is set, codeowners will use that path to generate the `CODEOWNERS` file. For example, `CODEOWNERS_PATH=docs` will generate `docs/CODEOWNERS`.
+If `codeowners_path` is set in `code_ownership.yml` codeowners will use that path to generate the `CODEOWNERS` file. For example, `codeowners_path: docs` will generate `docs/CODEOWNERS`.
