tidy *ale-html-tidy*
+`tidy` is a console application which corrects and cleans up HTML and XML
+documents by fixing markup errors and upgrading legacy code to modern
+standards.
+
+Note:
+`/usr/bin/tidy` on macOS (installed by default) is too old. It was released
+on 31 Oct 2006. It does not consider modern HTML specs (HTML5) and shows
+outdated warnings. So |ale| ignores `/usr/bin/tidy` on macOS.
+
+To use `tidy` on macOS, please install the latest version with Homebrew:
+>
+ $ brew install tidy-html5
+<
+`/usr/local/bin/tidy` is installed.
