+config to root, `app/` or `app/styles`.
+
+You can specify direct path to config by `config` option
+or `BROWSERSLIST_CONFIG` environment variables.
+
+## Environment Variables
+
+If some tool use Browserslist inside, you can change browsers settings
+by [environment variables]:
+
+* `BROWSERSLIST` with browsers queries.
+
+   ```sh
+  BROWSERSLIST="> 5%" gulp css

+
+* `BROWSERSLIST_CONFIG` with path to config file.
