+MicroPython language and implementation
+=======================================
+
+MicroPython aims to implement the Python 3.4 standard (with selected
+features from later versions) with respect to language syntax, and most
+of the features of MicroPython are identical to those described by the
+"Language Reference" documentation at
+`docs.python.org <https://docs.python.org/3/reference/index.html>`_.
+
+The MicroPython standard library is described in the
+:ref:`corresponding chapter <micropython_lib>`. The :ref:`cpython_diffs`
+chapter describes differences between MicroPython and CPython (which
+mostly concern standard library and types, but also some language-level
+features).
+
+This chapter describes features and peculiarities of MicroPython
+implementation and the best practices to use them.
