-Up to this point, we are clear on the concepts related to the Pomodoro Technique and the steps to develop a Spyder plugin. Now, we present a minimal plan to identify the features that will be displayed in Spyder once the plugin is implemented. As figures 1 and 2 show, there will be features in the toolbar, status bar, and the preferences window. An explanation of each feature is provided below.

 * ``setup.py``. It helps you install, package and distribute your plugin with ``setuptools``, the standard for distributing Python Modules.
