+ **Reinstalling R package and running 'make clean'**
+
+ When you will make changes to the Arrow C++ part of the code, also
+ called libarrow, you will need to:
+
+ #. reinstall libarrow
+ #. run ``make clean`` or ``git clean -fdx .``
Review comment:
``make clean`` and ``git clean -fdx .`` do totally different things to
each other so I don't think the phrasing is quite right here. I've never run
``git clean -fdx .`` while doing dev work (it could be useful, but isn't
essential given I just had to google what it was)
