-This library contains getters for useful semantic symbols. Because `cmd.exe` on
-Windows can't display Unicode, it also provides a mode where the symbols are
-replaced with plain-ASCII equivalents.
+This library contains getters for useful Unicode glyphs as well as plain ASCII
+alternatives. It's intended to be used in command-line applications that may run
+on Windows and libraries that may be used by those applications.
+
+We recommend that you import this library with the prefix "glyph". For example:
+
+```dart
+import 'package:term_glyph/term_glyph.dart' as glyph;
+
+/// Formats [items] into a bulleted list, with one item per line.
+String bulletedList(List<String> items) =>
+    items.map((item) => "${glyph.bullet} $item").join("\n");
+```
+
+## ASCII Mode
+
+The default Windows `cmd.exe` shell is unable to display Unicode characters, so
+this package is able to transparently switch its glyphs to ASCII alternatives by
+setting [the `ascii` attribute][ascii]. When this attribute is `true`, all
+glyphs use ASCII characters instead. It currently defaults to `false`, although
+in the future it may default to `true` for applications running on the Dart VM
+on Windows. For example:
+
+[ascii]: https://www.dartdocs.org/documentation/term_glyph/latest/term_glyph/ascii.html
+
+```dart
+import 'dart:io';
+
+import 'package:term_glyph/term_glyph.dart' as glyph;
+
+void main() {
+  glyph.ascii = Platform.isWindows;
+
+  // Prints "Unicode => ASCII" on Windows, "Unicode ━▶ ASCII" everywhere else.
+  print("Unicode ${glyph.rightArrow} ASCII");
+}
+```
+
+All ASCII glyphs are guaranteed to be the same number of characters as the
+corresponding Unicode glyphs, so that they line up properly when printed on a
+terminal. The specific ASCII text for a given Unicode glyph may change over
+time; this is not considered a breaking change.
