+MicroPython Standard Library
+============================
+Pycardium contains some modules from the MicroPython standard library. These
+are:
+
+.. py:module:: ubinascii
+
+``ubinascii``
+-------------
+Refer to the official `MicroPython docs for ubinascii`_.
+
+.. _MicroPython docs for ubinascii: http://docs.micropython.org/en/latest/library/ubinascii.html
+
+.. py:module:: ucollections
+
+``ucollections``
+----------------
+
+.. py:function:: namedtuple(...)
+
+ See the official `MicroPython docs for namedtuple`_ for details.
+
+ .. _MicroPython docs for namedtuple: http://docs.micropython.org/en/latest/library/ucollections.html#ucollections.namedtuple
+
+.. py:module:: uerrno
+
+``uerrno``
+----------
+Refer to the offical `MicroPython docs for uerrno`_.
+
+.. _MicroPython docs for uerrno: http://docs.micropython.org/en/latest/library/uerrno.html
+
+.. py:module:: uheapq
+
+``uheapq``
+----------
+Refer to the offical `MicroPython docs for uheapq`_.
+
+.. _MicroPython docs for uheapq: http://docs.micropython.org/en/latest/library/uheapq.html
+
+.. py:module:: uio
+
+``uio``
+-------
+Refer to the offical `MicroPython docs for uio`_.
+
+.. _MicroPython docs for uio: http://docs.micropython.org/en/latest/library/uio.html
+
+.. py:module:: ujson
+
+``ujson``
+---------
+Refer to the offical `MicroPython docs for ujson`_.
+
+.. _MicroPython docs for ujson: http://docs.micropython.org/en/latest/library/ujson.html
+
+.. py:module:: urandom
+
+``urandom``
+-----------
+Pseudo-random number generator.
+
+.. py:function:: choice(seq)
+
+ Return a random element from the non-empty sequence ``seq``.
+
+.. py:function:: getrandbits(k)
+
+ Returns a Python integer with ``k`` random bits.
+
+.. py:function:: randint(a, b)
+
+ Return a random integer ``N`` such that ``a <= N <= b``. Alias for
+ :py:func:`randrange(a, b+1) <urandom.randrange>`.
+
+.. py:function:: random()
+
+ Return the next random floating point number in the range [0.0, 1.0).
+
+.. py:function:: randrange(start, stop, [step])
+
+.. py:function:: randrange(stop)
+ :noindex:
+
+ Return a randomly selected element from ``range(start, stop, step)``. This
+ is equivalent to ``urandom.choice(range(start, stop, step))``, but doesn’t
+ actually build a range object.
+
+ The positional argument pattern matches that of ``range()``. Keyword
+ arguments should not be used because the function may use them in unexpected
+ ways.
+
+.. py:function:: seed(n)
+
+ Seed the pseudo-random number generator from ``n``.
+
+ .. note::
+
+ CPython does not provide a :py:func:`seed` function. This is a
+ difference in the MicroPython implementation.
+
+.. py:function:: uniform(a, b)
+
+ Return a random floating point number ``N`` such that ``a <= N <= b`` for
+ ``a <= b`` and ``b <= N <= a`` for ``b < a``.
+
+ The end-point value ``b`` may or may not be included in the range depending
+ on floating-point rounding in the equation ``a + (b-a) * random()``.
+
+.. py:module:: ure
+
+``ure``
+-------
+Minimal regular expression library. Refer to the offical `MicroPython docs for ure`_.
+
+.. _MicroPython docs for ure: http://docs.micropython.org/en/latest/library/ure.html
+
+.. py:module:: ustruct
+
+``ustruct``
+-----------
+Refer to the offical `MicroPython docs for ustruct`_.
+
+.. _MicroPython docs for ustruct: http://docs.micropython.org/en/latest/library/ustruct.html
+
+``utime``
+---------
+``utime`` contains non-standard functions as well. Please refer to our
+dedicated :py:mod:`utime` docs.
+
+
+Python Standard Library
+=======================
+Additionally to the MicroPython module, Pycardium contains a subset of the
+CPython standard library, as implemented by `micropython-lib`_. The following
+modules are included:
+
+.. _micropython-lib: https://github.com/micropython/micropython-lib
+
+.. py:module:: collections
+
+``collections``
+---------------
+Collections module.
+
+.. py:module:: contextlib
+
+``contextlib``
+--------------
+Contextlib module.
+
+.. py:module:: functools
+
+``functools``
+-------------
+Functools module.
+
+.. py:module:: itertools
+
+``itertools``
+-------------
+Itertools module.
+
+.. warning::
+
+ :py:func:`itertools.tee` is not implemented correctly.
+
+.. py:module:: string
+
+``string``
+----------
+String module.
+
+.. py:module:: struct
+
+``struct``
+----------
+Struct module.
+
+.. py:module:: uuid
+
+``uuid``
+--------
+
+.. py:class:: uuid.UUID(hex=None, bytes=None, int=None, version=None)
+
+ Create a new UUID object.
+
+ Exactly one of ``hex``, ``bytes``, or ``int`` must be given. The
+ ``version`` argument is optional; if given, the resulting UUID will have its
+ variant and version set according to RFC 4122, overriding the given ``hex``,
+ ``bytes``, or ``int``.
+
+ **Examples**:
+
+ .. code-block:: python
+
+ UUID('{12345678-1234-5678-1234-567812345678}')
+ UUID('12345678123456781234567812345678')
+ UUID('urn:uuid:12345678-1234-5678-1234-567812345678')
+ UUID(bytes='\x12\x34\x56\x78' * 4)
+ UUID(int=0x12345678123456781234567812345678)
+
+ .. py:attribute:: bytes
+
+ UUID as ``bytes()`` object
+
+ .. py:attribute:: node
+
+ Node of this UUID
+
+ .. py:attribute:: hex
+
+ Hex-String representation of this UUID
+
+ .. py:attribute:: version
+
+ UUID version accordiung to RFC 4122
+
+.. py:function:: uuid.uuid4():
+
+ Generate a new UUID version 4 (random UUID).
+
+ .. todo::
+
+ This function is not yet usable because we don't have
+ :py:func:`os.urandom` yet.
