+Building on macOS
+-----------------
+
+The stock ncurses libraries on macOS don't include the wide libraries. Thus the full ncurses version needs to be installed with [Homebrew](https://brew.sh/). Homebrew installs ncurses below ```/usr/local/opt/ncurses```, where the dub configuration will pick it up.
+
+First install Homebrew using the instructions on the web site, then you can add the ncurses package with
+
+````
+brew install ncurses
+````
