+//! This is the place where everything editor-related is stored (data-wise) and displayed (ui-wise).
+//! The main point of interest in this crate is [`Editor`] type, which is used in every other Zed part as a user input element.
+//! It comes in different flavors: single line, multiline and a fixed height one.
+//!
+//! Editor contains of multiple large submodules:
+//! * [`element`] — the place where all rendering happens
+//! * [`display_map`] - chunks up text in the editor into the logical blocks, establishes coordinates and mapping between each of them.
+//!   Contains all metadata related to text transformations (folds, fake inlay text insertions, soft wraps, tab markup, etc.).
+//! * [`inlay_hint_cache`] - is a storage of inlay hints out of LSP requests, responsible for querying LSP and updating `display_map`'s state accordingly.
+//!
+//! All other submodules and structs are mostly concerned with holding editor data about the way it displays current buffer region(s).
+//!
+//! If you're looking to improve Vim mode, you should check out Vim crate that wraps Editor and overrides it's behaviour.
