What does drafting redlines mean?

Drafting redlines refers to the process of creating a version of a document that highlights changes, edits, or comments compared to a previous version. This is typically done using Word processing software that allows users to track changes, making it easy to see what has been added, deleted, or modified. Redlines are commonly used in legal, business, and collaborative contexts to facilitate discussions and negotiations around document revisions. The term "redline" comes from the traditional practice of using red ink to mark changes.
