+Why Pendulum?
+=============
+
+Native ``datetime`` instances are enough for basic cases but when you face more complex use-cases
+they often show limitations and are not so intuitive to work with.
+``Pendulum`` provides a cleaner and more easy to use API while still relying on the standard library.
+So it's still ``datetime`` but better.
+
+Unlike other datetime libraries for Python, Pendulum is a drop-in replacement
+for the standard ``datetime`` class (it inherits from it), so, basically, you can replace all your ``datetime``
+instances by ``DateTime`` instances in you code (exceptions exist for libraries that check
+the type of the objects by using the ``type`` function like ``sqlite3`` or ``PyMySQL`` for instance).
+
+It also removes the notion of naive datetimes: each ``Pendulum`` instance is timezone-aware
+and by default in ``UTC`` for ease of use.
+
+Pendulum also improves the standard ``timedelta`` class by providing more intuitive methods and properties.
+
+
+Why not Arrow?
+==============
+
+Arrow is the most popular datetime library for Python right now, however its behavior
+and API can be erratic and unpredictable. The ``get()`` method can receive pretty much anything
+and it will try its best to return something while silently failing to handle some cases:
+
+.. code-block:: python
+
+    arrow.get('2016-1-17')
+    # <Arrow [2016-01-01T00:00:00+00:00]>
+
+    pendulum.parse('2016-1-17')
+    # <Pendulum [2016-01-17T00:00:00+00:00]>
+
+    arrow.get('20160413')
+    # <Arrow [1970-08-22T08:06:53+00:00]>
+
+    pendulum.parse('20160413')
+    # <Pendulum [2016-04-13T00:00:00+00:00]>
+
+    arrow.get('2016-W07-5')
+    # <Arrow [2016-01-01T00:00:00+00:00]>
+
+    pendulum.parse('2016-W07-5')
+    # <Pendulum [2016-02-19T00:00:00+00:00]>
+
+    # Working with DST
+    just_before = arrow.Arrow(2013, 3, 31, 1, 59, 59, 999999, 'Europe/Paris')
+    just_after = just_before.replace(microseconds=1)
+    '2013-03-31T02:00:00+02:00'
+    # Should be 2013-03-31T03:00:00+02:00
+
+    (just_after.to('utc') - just_before.to('utc')).total_seconds()
+    -3599.999999
+    # Should be 1e-06
+
+    just_before = pendulum.datetime(2013, 3, 31, 1, 59, 59, 999999, 'Europe/Paris')
+    just_after = just_before.add(microseconds=1)
+    '2013-03-31T03:00:00+02:00'
+
+    (just_after.in_timezone('utc') - just_before.in_timezone('utc')).total_seconds()
+    1e-06
+
+Those are a few examples showing that Arrow cannot always be trusted to have a consistent
+behavior with the data you are passing to it.
+
+
+Limitations
+===========
+
+Even though the ``DateTime`` class is a subclass of ``datetime`` there are some rare cases where
+it can't replace the native class directly. Here is a list (non-exhaustive) of the reported cases with
+a possible solution, if any:
+
+* ``sqlite3`` will use the ``type()`` function to determine the type of the object by default. To work around it you can register a new adapter:
+
+.. code-block:: python
+
+    from pendulum import DateTime
+    from sqlite3 import register_adapter
+
+    register_adapter(DateTime, lambda val: val.isoformat(' '))
+
+* ``mysqlclient`` (former ``MySQLdb``) and ``PyMySQL`` will use the ``type()`` function to determine the type of the object by default. To work around it you can register a new adapter:
+
+.. code-block:: python
+
+    import MySQLdb.converters
+    import pymysql.converters
+
+    from pendulum import DateTime
+
+    MySQLdb.converters.conversions[DateTime] = MySQLdb.converters.DateTime2literal
+    pymysql.converters.conversions[DateTime] = pymysql.converters.escape_datetime
+
+* ``django`` will use the ``isoformat()`` method to store datetimes in the database. However since ``pendulum`` is always timezone aware the offset information will always be returned by ``isoformat()`` raising an error, at least for MySQL databases. To work around it you can either create your own ``DateTimeField`` or use the previous workaround for ``MySQLdb``:
+
+.. code-block:: python
+
+    from django.db.models import DateTimeField as BaseDateTimeField
+    from pendulum import DateTime
+
+
+    class DateTimeField(BaseDateTimeField):
+
+        def value_to_string(self, obj):
+            val = self.value_from_object(obj)
+
+            if isinstance(value, DateTime):
+                return value.to_datetime_string()
+
+            return '' if val is None else val.isoformat()
+

+Contributing
+============
+
+Contributions are welcome, especially with localization.
+
+Getting started
+---------------
+
+To work on the Pendulum codebase, you'll want to clone the project locally
+and install the required depedendencies via `poetry <https://poetry.eustace.io>`_.
+
+.. code-block:: bash
+
+    $ git clone git@github.com:sdispater/pendulum.git
+    $ poetry install
+
+Localization
+------------
+
+If you want to help with localization, there are two different cases: the locale already exists
+or not.
+
+If the locale does not exist you will need to create it by using the ``clock`` utility:
+
+.. code-block:: bash
+
+    ./clock locale create <your-locale>
+
+It will generate a directory in ``pendulum/locales`` named after your locale, with the following
+structure:
+
+.. code-block:: text
+
+    <your-locale>/
+        - custom.py
+        - locale.py
+
+The ``locale.py`` file must not be modified. It contains the translations provided by
+the CLDR database.
+
+The ``custom.py`` file is the one you want to modify. It contains the data needed
+by Pendulum that are not provided by the CLDR database. You can take the `en <https://github.com/sdispater/pendulum/tree/master/pendulum/locales/en/custom.py>`_
+data as a reference to see which data is needed.
+
+You should also add tests for the created or modified locale.
