 This crate allows to format [chrono](https://github.com/chronotope/chrono) dates with localized months and week days.
 
-It's in early development and everything could change. Please don't use. Yet!
+It's in early development and everything could change. Use with caution!
+
+## Usage
+
+Put this in your Cargo.toml:
+
+```
+[dependencies]
+chrono = "0.4"
+chrono_locale = "0.1"
+```
+
+Then put this in your `lib.rs` or `main.rs`:
+
+```
+extern crate chrono;
+extern crate chrono_locale;
+
+use chrono::prelude::*;
+use chrono_locale::LocaleDate;
+```
+
+You can choose to import just parts of chrono instead of the whole prelude.
+Please see ['chrono`'s documentation](https://docs.rs/chrono/).
+
+To format a chrono `Date` or `DateTime` object, you can use the `formatl` method:
+
+```
+let dt = FixedOffset::east(34200).ymd(2001, 7, 8).and_hms_nano(0, 34, 59, 1_026_490_708);
+println!("{}", dt.formatl("%c", "fr"));
+```
+
+All of [chrono's formatting placeholders](https://docs.rs/chrono/0.4.6/chrono/format/strftime/index.html)
+work except for `%3f`, `%6f` and `%9f` (but `%.3f`, `%.6f` and `%.9f` work normally)
