+Installation
+------------
+
+The core parser is written in :code:`Cython`, which is a superset of Python but
+compiles the input down to a C extension which can then be imported in normal
+Python code.
+
+The compiled C parser code is included in the PyPI package, hence the
+installation requires a working C compiler.
