-.. note::
-    If you bind your local repo for the first time, you have to build the C extensions afterwards.
-    Run the following command inside the container::
-
-        python setup.py build_ext -j 4
+.. code-block:: bash
 
-    You need to rebuild the C extensions anytime the Cython code in ``pandas/_libs`` changes.
-    This most frequently occurs when changing or merging branches.
