-- `parse_structure` returns a root whose kind is `SourceFile`.
-- `parse_expression` returns a root whose kind is `ExpressionFragment`.
+- `parse_structure` returns a root whose kind is `Impls`.
+- `parse_expression` returns a root whose kind is `Expression`.
 
 Successful results can be lowered with `ParseResult::to_impls` and
 `ParseResult::to_expr`, respectively. Calling a lowering method for the other
 root kind returns a diagnostic.
 
 ## Source Text
 
-CST nodes do not own the original source text. Keep the original `source` and
-pass it to `CstNode::text(source)` when reconstructing text for a node. The
-method returns a zero-copy `StringView` backed by that source; call
-`to_owned()` explicitly if an owned `String` is required.
+CST nodes do not own the original source text. 
 
 `CstNode.source_span` is a pair of UTF-16 code-unit offsets: an inclusive start
 and an exclusive end. They can be used directly as `String`/`StringView`
-slicing offsets. Keep using the same source string when calling `text(source)`.
+slicing offsets. 
 
 Parse source text with one of the two entry points so every node span refers to
 the original source string.
