-//! To do.
+//! Non-lazy continuation.
+//!
+//! This is a tiny helper that [flow][] constructs can use to make sure that
+//! the following line is not lazy.
+//! For example, [html (flow)][html_flow] and code ([fenced][code_fenced],
+//! [indented][code_indented]), stop when next line is lazy.
+//!
+//! [flow]: crate::content::flow
+//! [code_fenced]: crate::construct::code_fenced
+//! [code_indented]: crate::construct::code_indented
+//! [html_flow]: crate::construct::html_flow
