+## Backends
 
-## Implementation and Goals
+This library uses different backends on different platforms:
 
-* Wraps around [ICU4X](https://github.com/unicode-org/icu4x) on native or web
-  platforms.
-* Wraps around the built-in browser functionalities on the web.
-    * Select which locales you want to use the browser for through an ``.
+*   **ICU4X**: Wraps [ICU4X](https://github.com/unicode-org/icu4x) to provide i18n functionality on both native platforms.
+*   **ECMA / Browser**: Wraps the browser's built-in [`Intl`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Intl) functionalities for web-only applications, reducing bundle size.
 
-## Example
+## Installation
 
-The functionalities are called through getters on an `Intl` instance, i.e.
+Add `intl4x` to your `pubspec.yaml`:
+
+```shell
+dart pub add intl4x
+```
+
+
+## Limitations
+
+There are still some features missing:
+
+ * Compact, percent, unit, and currency formatting.
+ * Display names for calendar, currency, date time fields, and scripts.
+
+## Features
+
+### Date & Time Formatting
+
+Format `DateTime` objects into locale-sensitive strings for dates, times, and time zones.
+
+```dart
+import 'package:intl4x/datetime_format.dart';
+
+void main() {
+  final dateTime = DateTime(2024, 7, 1, 8, 50, 07);
+  final germanLocale = Locale.parse('de-DE');
+
+  final formatter = DateTimeFormat.yearMonthDayTime(
+    locale: germanLocale,
+    length: DateTimeLength.long,
+  ).withTimeZoneLong();
+
+  // Format with a specific timezone
+  print(formatter.format(dateTime, 'Europe/Berlin')); 
+  // prints "1. Juli 2024 um 10:50:07 Mitteleuropäische Sommerzeit"
+}
+```
+
+### Number Formatting
+
+Format numbers as decimals, percentages, or in compact form with locale-specific rules.
 
 ```dart
 import 'package:intl4x/number_format.dart';
 
 void main() {
-  final numberFormat = NumberFormat.percent(locale: Locale.parse('en-US'));
+  final locale = Locale.parse('en-US');
 
-  print(numberFormat.format(0.5)); // prints 50%
+  final compactFormat = NumberFormat.compact(locale: locale);
+  print(compactFormat.format(12345)); // "12K"
+
+  final percentFormat = NumberFormat.percent(locale: locale);
+  print(percentFormat.format(0.987)); // "99%"
 }
 ```
 
-## Installation
+### Collation (String Sorting)
 
-The easiest setup is 
+Sort lists of strings with locale-aware collation.
+
+```dart
+import 'package:intl4x/collation.dart';
+
+void main() {
+  final list = ['Z', 'a', 'z', 'ä'];
+  final german = Collation(locale: Locale.parse('de-DE'));
+
+  list.sort(german.compare);
+
+  print(list); // prints "[a, ä, z, Z]"
+}
 ```
-dart pub add intl4x
-dart run ...
+
+### Display Names
+
+Get localized display names for locales, regions, scripts, and currencies.
+
+```dart
+import 'package:intl4x/display_names.dart';
+
+void main() {
+  final displayNames = DisplayNames(locale: Locale.parse('en'));
+
+  print(displayNames.ofLocale(Locale.parse('fr-CA'))); // "Canadian French"
+  print(displayNames.ofRegion('419')); // "Latin America"
+}
 ```
-This will download the binaries from Github
+
+### List Formatting
+
+Join lists of items into a grammatically correct, locale-sensitive string.
+
+```dart
+import 'package:intl4x/list_format.dart';
+
+void main() {
+  final list = ['apples', 'bananas', 'oranges'];
+  final english = Locale.parse('en');
+  
+  print(list.joinAnd(locale: english)); // "apples, bananas, and oranges"
+  print(list.joinOr(locale: english));  // "apples, bananas, or oranges"
+}
+```
+
+### Plural Rules
+
+Select the correct plural category for a given number based on locale rules (e.g., `one`, `few`, `many`).
+
+```dart
+import 'package:intl4x/plural_rules.dart';
+
+void main() {
+  final rules = PluralRules(
+    locale: Locale.parse('en-US'),
+    type: PluralType.ordinal,
+  );
+
+  print(rules.select(1)); // PluralCategory.one (st)
+  print(rules.select(2)); // PluralCategory.two (nd)
+  print(rules.select(3)); // PluralCategory.few (rd)
+  print(rules.select(4)); // PluralCategory.other (th)
+}
+```
+
+### Case Mapping
+
+Change the case of strings according to locale-specific rules.
+
+```dart
+import 'package:intl4x/case_mapping.dart';
+
+void main() {
+  final tr = Locale.parse('tr');
+  final en = Locale.parse('en');
+
+  final upper = 'TICKET';
+  print(upper.toLocaleLowerCase(en)); // ticket
+  print(upper.toLocaleLowerCase(tr)); // tıcket
+  
+  final lower = 'i';
+  print(lower.toLocaleUpperCase(en)); // I
+  print(lower.toLocaleUpperCase(tr)); // İ
+}
+```
