 A. Preparation
 ---------------
 
-1. Install ``py.test``:: ``pip install pytest``

-B. Vector unary ``-``
----------------------
+B. Vector negation
+------------------
 
 1. Go to ``exercises/vector`` directory
 
-2. Run the tests: ``py.test``
+2. Run test for unary ``-`` with the ``-x`` option to stop at first error or failure:
 
-3. Open the ``vector/vector.py``.
+.. code-block:: shell
+
+    $ py.test -x test_vector_neg.py
+
+3. Edit ``vector.py`` to implement a ``__neg__`` method for unary negation. That method should return a new ``Vector`` instance with each component negated. See ``test_vector_neg.py`` for the expected behavior.

+
+C. Vector addition
+------------------
+
+1. Run tests for vector addition ``+`` with the ``-x`` option to stop at first error or failure:
+
+.. code-block:: shell
+
+    $ py.test -x test_vector_add.py
+
+2. Edit ``vector.py`` to implement a ``__add__`` method for vector addition. That method should return a new ``Vector`` instance with each component of ``self`` added to the corresponding component of ``other``. See ``test_vector_add.py`` for the expected behaviors.
