Google Docs is the top online document editor, hands down. If you're working on document, you can quickly create an outline in Google Docs.

If you want to create a document outline in Google Docs, here is how you can do that. You do not need to use third-party add-ons since Google Docs has the option by default.

Without adding headings, you can't create an outline or table of contents in Google Docs. Headings let you easily jump through different sections or move straight to the summary in long documents.

You can add a summary to any Google Doc by opening the document's outline. If your Google Doc is long enough, you can use a computer-generated summary instead of writing your own.
