-Example:
+To replicate functionality in `terraform_docs` hook:
 
-```yaml
-- id: terraform_docs_replace
-  args:
-    - --sort-by-required
-    - --dest=TEST.md
-```
+1. Create `.terraform-docs.yml` in the repo root with the following content:
+
+    ```yaml
+    formatter: "markdown"
+
+    output:
+    file: "README.md"
+    mode: replace
+    template: |-
+        {{/** End of file fixer */}}
+    ```
+
+2. Replace `terraform_docs_replace` hook config in `.pre-commit-config.yaml` with:
+
+    ```yaml
+    - id: terraform_docs
+    args:
+        - --args=--config=.terraform-docs.yml
