 ## Writing Your Own Functions
 
-The project supports write functions in bash/js/python.
+You can write functions in bash/javascript/python.
+
+`llm-functions` will automatic generate function declarations from comments. Refer to `demo_tool.{sh,js,py}` for examples of how to use comments for autogeneration of declarations.

-`llm-functions` will automatic generate function declaration.json from [comment tags](https://github.com/sigoden/argc?tab=readme-ov-file#comment-tags).
-
-The relationship between comment tags and parameters in function declarations is as follows:
-
-```sh
-# @flag --boolean                   Parameter `{"type": "boolean"}`
-# @option --string                  Parameter `{"type": "string"}`
-# @option --string-enum[foo|bar]    Parameter `{"type": "string", "enum": ["foo", "bar"]}`
-# @option --integer <INT>           Parameter `{"type": "integer"}`
-# @option --number <NUM>            Parameter `{"type": "number"}`
-# @option --array* <VALUE>          Parameter `{"type": "array", "items": {"type":"string"}}`
-# @option --scalar-required!        Use `!` to mark a scalar parameter as required.
-# @option --array-required+         Use `+` to mark a array parameter as required
