-Types of datetime (and why they're important)
----------------------------------------------
-
-🚧 **NOT YET FULLY IMPLEMENTED** 🚧
-
-**Whenever** distinguishes these types:
-
-1. **Naive** datetime: A simple type that isn't aware of any timezone or
-   UTC offset.
-2. **UTC**-only datetime: A fast and efficient type for when you
-   *only* want to deal with UTC.
-3. **Offset** datetime: A datetime with a *fixed* offset from UTC.
-4. **Zoned** datetime: A datetime within a timezone, often with a variable
-   UTC offset. Zoned datetimes may be ambiguous or non-existent.

+
+Best of all, **whenever** is *boring*. It doesn't do any fancy things.
+It's just five dead-simple classes thinly wrapping the standard library.
+There's no function over 10 lines long, and no dependencies.
+The goal is to give you peace of mind.

 Quickstart
 ----------
 
-**Most of the functionality it not yet implemented.**
-Some basic UTC functionality is already available though:
+🚧 WORK IN PROGRESS 🚧
+
+Whenever provides these datetime types:
 
 .. code-block:: python
 
-   from whenever.utc import DateTime
-   from whenever import Some, Nothing
+   from whenever import (
+       UTCDateTime, OffsetDateTime, ZonedDateTime, LocalDateTime, NaiveDateTime
+   )
+
+and here's how you can use them:
+
++-----------------------+-----+--------+-------+-------+-------+
+| Feature               |         Aware                | Naive |

++-----------------------+-----+--------+-------+-------+-------+
+
+- **UTCDateTime** is always UTC: simple, fast, and unambiguous.
+  It's great if you're storing when something happened (or will happen) regardless of location.
+
+  *Example use cases:* The "created" timestamp of a blog post
+  the scheduled start of a livestream.
+
+  .. code-block:: python
+
+     py311_release_livestream = UTCDateTime(2022, 10, 24, hour=17)
+
+- **OffsetDateTime** defines a local time using a UTC offset.
+  This is great if you're storing when something happened at a specific location.
+  It's less suitable for *future* events though,
+  because the UTC offset may change (e.g. due to daylight savings time).
+  For this reason, you also cannot add/subtract a ``timedelta``
+  — the offset may have changed!
+
+  *Example use case:* Time at which a local event occurred.
+
+  .. code-block:: python
+
+     from whenever import hours  # alias for timedelta(hours=...)
+
+     pycon23_started = OffsetDateTime(2023, 4, 21, hour=9, offset=hours(-6))
+
+- **ZonedDateTime** accounts for timezones and their variable UTC offset.
+  When the clock is set backwards, times occurs twice:
+  a ``fold`` attribute is required to explicitly `resolve these ambiguities <https://docs.python.org/3/library/datetime.html#datetime.datetime.fold>`_.
+
+  *Example use case:* The time of an appointment at a specific location.
+
+  .. code-block:: python
+
+     from zoneinfo import ZoneInfo  # timezones from the standard library 🎉
+     london = ZoneInfo("Europe/London")
+
+     # always at 11:00 in London, regardless of the offset
+     changing_the_guard = ZonedDateTime(2024, 12, 8, hour=11, tz=london, fold=0)
+
+     # With `expect_unambiguous()` you can omit `fold`,
+     # but you'll get a ValueError in ambiguous cases.
+     changing_the_guard = ZonedDatetime.expect_unambiguous(2024, 12, 8, hour=11, tz=london)
+
+- **LocalDateTime** is a datetime in the system local timezone.
+  This type is great for representing a time on the current system.
+
+  *Example use case:* An alarm clock app which runs on the user's system.
+
+  .. code-block:: python
+
+     print(f"Your timer will go off at {LocalDateTime.now() + hours(1)}.")
+
+
+- **NaiveDateTime** isn't aware of timezones or UTC offset.
+  Use this if you need a datetime type detached from the complexities of the real world.
+
+  *Example use case:* modeling time in a city simulation game.
+
+  .. code-block:: python
+
+     simulation_start = NaiveDateTime(1900, 1, 1, hour=0)
+
+
+Why not...?
+-----------
+
+The standard library
+~~~~~~~~~~~~~~~~~~~~
+
+While it has all the functionality you need, it has many pitfalls:
+
+- You can't be certain if ``datetime`` is naive or aware
+  without running the code.
+- ``datetime`` inherits from ``date``,
+  `giving unexpected behaviour <https://github.com/python/typeshed/issues/4802>`_.
+- adding/subtracting ``timedelta`` does not account for daylight savings time.
+- naive datetimes implicitly function as local datetimes,
+  which is often not what you want.
+- ``fold`` defaults to 0 for ambiguous datetimes, instead of forcing you to be explicit.
+- Some outdated methods still exist (although they are deprecated),
+  such as ``datetime.utcnow()``
+
+Pendulum
+~~~~~~~~
+
+Although fast and full-featured:
+
+- aware/naive datetimes cannot be distinguished at type-checking time.
+- its types inherit from the standard library ``datetime``,
+  which brings along a lot of baggage and potential pitfalls.
+
+DateType
+~~~~~~~~
+
+DateType fixes most of the naive/aware issues at type-checking time, but:
+
+- it doesn't enforce correctness at runtime.
+- it doesn't distinguish offset and zoned datetimes.
+- it isn't able to *fully* type-check all `cases <https://github.com/glyph/DateType/blob/0ff07493bc2a13d6fafdba400e52ee919beeb093/tryit.py#L31>`_.
 
-   # Explicit types for functional/Rust-style error handling
-   d = DateTime.new(2020, 1, 1, 12, 0, 0).unwrap()
+Heliclockter
+~~~~~~~~~~~~
 
-   match DateTime.parse("2020-08-15T12:08:30Z"):
-       case Some(d2) if d2 > d:
-           print('parsed a datetime after 2020-01-01T12:00:00Z')
-       case Nothing():
-           print('failed to parse')
+This library is a lot more explicit about the different types of datetimes,
+however:
 
-   d.timestamp()  # UNIX timestamp
-   d.to_py()  # convert to Python's datetime.datetime
+- it doesn't have a separate class for UTC and fixed-offset datetimes.
+- its types inherit from the standard library ``datetime``,
+  which brings along a lot of baggage and potential pitfalls.
+- No enorcement on resolving ambiguous datetimes.
