# Fill syntax information in CotEditor on Mac

A syntax definition can have metadata, such as author name or version to manage it.

To check or modify the information of a syntax definition, select Syntax Info from the list on the left of the syntax editor. See Define a syntax for how to open the syntax editor.

The metadata of a syntax definition can be set as follows:

Field | Description
--- | ---
Version | The version of the syntax. We recommend using the semantic versioning.
Last modified | The last modified date of the syntax. We recommend using the format `YYYY-MM-DD`.
Distribution URL | The URL of a web page in which the syntax is distributed.
Author | The author of the syntax.
License | The license of the syntax.
Description | The additional information on the syntax.

This information might be useful if you want to share your own syntax. You can leave fields also empty.
