 //! # Steps
 //! - **Parsing:** The parsing step first transforms a plain string into an
-//!   [iterator of tokens][tokens]. This token stream is [parsed] into a [syntax
-//!   tree]. The structures describing the tree can be found in the [syntax]
-//!   module.
-//! - **Evaluation:** The next step is to [evaluate] the syntax tree. This
-//!   produces a [module], consisting of a scope of values that were exported by
-//!   the module and a template with the contents of the module. This template
-//!   can be [instantiated] in a state to produce a layout tree, a high-level,
-//!   fully styled representation of the document. The nodes of this tree are
+//!   [iterator of tokens][tokens]. This token stream is [parsed] into [markup].
+//!   The syntactical structures describing markup and embedded code can be
+//!   found in the [syntax] module.
+//! - **Evaluation:** The next step is to [evaluate] the markup. This produces a
+//!   [module], consisting of a scope of values that were exported by the code
+//!   and a template with the contents of the module. This template can be
+//!   [instantiated] in a state to produce a layout tree, a high-level, fully
+//!   styled representation of the document. The nodes of this tree are
 //!   self-contained and order-independent and thus much better suited for
-//!   layouting than a syntax tree.
+//!   layouting than the raw markup.
 //! - **Layouting:** Next, the tree is [layouted] into a portable version of the
 //!   typeset document. The output of this is a collection of [`Frame`]s (one
 //!   per page), ready for exporting.
 //! - **Exporting:** The finished layout can be exported into a supported
 //!   format. Currently, the only supported output format is [PDF].
