extensions, which means you need a C compiler. This process depends on which
platform you're using.

For Mac, the https://devguide.python.org/setup/#macos link actually has some explanation about installing XCode, so maybe for this one we can keep the link until we have better instructions.

I have replaced my Mac instructions with just the link above.

I've also changed formatting - happy to change back as well @jorisvandenbossche

Formatting looks good!

* Mac: From Xcode 4.2, the C compiler 'Clang' is the default compiler for
Mac OS X and new versions of Mac OS X should already have this installed. You
can check if you have Clang installed by typing ``clang --version`` in a
terminal. If you do not, you can install Clang by typing
``xcode-select --install`` in a terminal. Then follow the pop-up instructions
and agree to install the tools. You may also choose to install a different
C compiler if you wish.
* Unix: Some Linux distributions will come with with a C compiler. To find out
which compilers (and versions) are installed on your system::

# for Debian/Ubuntu:
dpkg --list | grep compiler
# for Red Hat/RHEL/CentOS/Fedora:
yum list installed | grep -i --color compiler

`GCC (GNU Compiler Collection) <https://gcc.gnu.org/>`_, is a widely used
compiler, which supports C and a number of other languages. If GCC is listed
as an installed compiler nothing more is required. If no C compiler is
installed (or you wish to install a newer version) you can install a compiler
(GCC in the example code below) with::

# for recent Debian/Ubuntu:
sudo apt install build-essential
# for Red Had/RHEL/CentOS/Fedora
yum groupinstall "Development Tools"

For other Linux distributions, consult your favourite search engine for
installation instructions.
