+    Used to set secrets from a file, supporting both `.env` and `YAML` formats. The file path can be either absolute or relative to the current working directory.
+
+    The file should contain secrets in the following formats:
+    - `key=value` for `.env` files
+    - `key: value` for YAML files
+
+    Comments can be written using `# comment` or `// comment`. Empty lines will be ignored during processing.
