 ## Quick start
 
 ```sh
-cmake -S . -B build
+cmake -S . -B build                      # TUI (default); add -DESSIM_FRONTEND=wx for the GUI
 cmake --build build -j
 ./build/essim
 ```
 
-The build is **layered**: `essim_core` is the frontend-agnostic business
-library (domain + importers + operations); the `essim` binary comes from a
-**frontend** under `src/frontends/<name>/` that links it. Select one with
-`-DESSIM_FRONTEND=<name>` (default `tui`); `-DESSIM_FRONTEND=none` builds the
-core + tests only, with no GUI toolkit fetched. Architecture in
-[`DESIGN.md`](DESIGN.md).
-
-The quick start above builds the **tui** (terminal) frontend. For the
-**wxWidgets GUI** instead (needs wxWidgets ≥ 3.2, see *Dependencies*):
-
-```sh
-cmake -S . -B build -DESSIM_FRONTEND=wx
-cmake --build build -j
-./build/essim
-```
-
-Switching `-DESSIM_FRONTEND` on an existing `build/` reconfigures it in place.
+Frontends: `tui` (terminal, default), `wx` (wxWidgets GUI), `none` (core +
+tests, no GUI toolkit). Architecture in [`DESIGN.md`](DESIGN.md).
