Problem: Documentation mentions bootstrap-buildout

Solution: Remove it, mention `pip`

A third item is the bootstrap.py file in ``bootstrap/bootstrap.py``. The
canonical location is at https://bootstrap.pypa.io/bootstrap-buildout.py,
(though it is unfortunate that it isn't named just ``bootstrap.py``). This
file is pulled automatically every 15 minutes from the bootstrap-release
branch. When a new buildout release is made, **the releaser** should update
the bootstrap-release branch, too.
The http://downloads.buildout.org/2/bootstrap.py location doesn't need to be

Installing from scratch

We recommend to install ``buildout`` via ``pip install`` inside a ``virtualenv``:

It will download the software needed to run Buildout and install it in

This has been the traditional approach to bootstrapping Buildout.
It was the best approach for a long time because the ``pip`` and
``easy_install`` commands usually weren't available. In the early
days, if ``easy_install`` was installed, it was likely to have an
incompatible version of setuptools, because Buildout and setuptools
were evolving rapidly, sometimes in lock step.
This approach fails from time to time, due to changes in setuptools or
`the package index <https://pypi.org/>`_ and has been a
source of breakage when automated systems depended on it.
It's also possible that this approach will stop being supported.
Buildout's bootstrapping script relies on setuptools' bootstrap
script, which was used to bootstrap ``easy_install``. Now that pip is
ubiquitous, there's no reason to bootstrap ``easy_install`` and
setuptools' bootstrapping script exists solely to support Buildout.
At some point, that may become too much of a maintenance burden, and
there may not be Buildout volunteers motivated to create a new
bootstrapping solution.
