Mu - A Simple Python Code Editor 
================================

**THIS PROJECT IS NO LONGER MAINTAINED**

.. image:: https://mu.readthedocs.io/en/latest/_images/logo.png

Mu is a simple code editor for beginner programmers based on extensive feedback
from teachers and learners. Having said that, Mu is for anyone who wants to use
a simple "no frills" editor. Most importantly, have fun!

Mu is a modal editor with modes for many different ways to use Python to create
cool and interesting things.

Mu is written in Python and works on Windows, macOS, Linux and Raspberry Pi.
The project's public facing website is
`https://codewith.mu/ <https://codewith.mu/>`_. We celebrate the work done by
users of mu at `https://madewith.mu/ <https://madewith.mu/>`_.

We have `extensive developer documentation <https://mu.readthedocs.io/>`_
including a guide for
`setting up a development environment <https://mu.readthedocs.io/en/latest/setup.html>`_, 
`contributor guidelines <https://mu.readthedocs.io/en/latest/contributing.html>`_ and
`some suggested first steps <https://mu.readthedocs.io/en/latest/first-steps.html>`_.

We want our community to be a friendly place. Therefore, we expect contributors
and collaborators to follow our
`Code of Conduct <https://mu.readthedocs.io/en/latest/code_of_conduct.html>`_.
