 SGLang supports two grammar backends:
 
-- [Outlines](https://github.com/dottxt-ai/outlines) (default): Supports JSON schema and regular expression constraints.
-- [XGrammar](https://github.com/mlc-ai/xgrammar): Supports JSON schema, regular expression, and EBNF constraints.

   - XGrammar currently uses the [GGML BNF format](https://github.com/ggerganov/llama.cpp/blob/master/grammars/README.md).
 
-Initialize the XGrammar backend using `--grammar-backend xgrammar` flag:
+If instead you want to initialize the Outlines backend, you can use `--grammar-backend outlines` flag:
 
 ```bash
