+``urandom`` - Random Number Generation
+======================================
+The :py:mod:`urandom` module allows you to generate random numbers. Please note that this module is currently only *seeded* with the TRNG and uses pseudo random numbers for later invocations.
+
+**Example**:
+
+.. code-block:: python
+
+   import urandom
+   print(urandom.random())
+
+.. py:function:: urandom.getrandbits(num)
+
+   Return random bits.
+
+   :param int num: Number of random bits to generate (max. 32)
+   :returns: An integer with numin bit randomly set.
+
+.. py:function:: urandom.seed(seed)
+
+   :param int seed: Integer to seed the random number generator with.
+
+.. py:function:: urandom.randrange(start, stop[, step])
+
+   Return a random number from the `range(start, stop, step)`.
+
+   :returns: A random number from the range.
+
+.. py:function:: urandom.randint(a,b)
+
+   Return a random integer `N` with `a <= N <= b`.
+
+   :returns: A random number from the range.
+
+.. py:function:: urandom.choice(seq)
+
+   Return a random element from the given sequence.
+
+   :returns: A random number from the sequence.
+
+.. py:function:: urandom.random()
+
+   Return a random floating point number `x` with `0 <= x < 1`.
+
+   :returns: A random number from the range.
+
+.. py:function:: urandom.uniform(a, b)
+
+   Return a random floating point number `x` with `a <= x <= b`.
+
+   :returns: A random number from the range.
