 All development dependencies can be installed by running::
 
-  $ pip install -r requirements/development.txt
+  $ pip install .[development]

 For example, when using the virtual environment library :code:`venv`::
 
-  $ python -m venv axelrod_development
-  $ source axelrod_development/bin/activate
-  $ pip install -r requirements/development.txt

-Alternatively, you can specify the development variant rather than the path::
-
   $ python -m venv axelrod_development
   $ source axelrod_development/bin/activate
   $ pip install .[development]
