Getting started notebook is outdated

For example here are the Installation instructions:

Installation

Running PyMC3 requires a working Python interpreter, either version 2.7 (or more recent) or 3.5 (or more recent); we recommend that new users install version 3.5. A complete Python installation for Mac OSX, Linux and Windows can most easily be obtained by downloading and installing the free Anaconda Python Distribution by ContinuumIO.

Let's keep in mind that this is without any doubt the most visited notebook in the docs, so even the tiniest changes can have a huge impact on the project overall.

It may also be worth to redeploy the docs right after this is updated, even if it's the only change since the last deployment.

Some specifics that jump to mind:

1. Probably it's better to just remove the find_MAP demonstration at this point? Maybe introduce prior and posterior predictive sampling instead?
2. This is severely outdated:

PyMC3, Stan (Stan Development Team, 2014), and the LaplacesDemon package for R are currently the only PP packages to offer HMC.

3. Variational inference is mentioned as a missing feature (and no reference to SMC either)

@ricardoV94 I'm interested in working for this. To begin with, the find_MAP demonstration has been removed through this pull request - #145

For the second point, what changes can be made?
Can you please explain the third point?
Thanks!

Is this issue still needed? The notebook mentioned is not in the main branch anymore.

Weird, it indeed seems to have gone. Couldn't find where it went either.

This is now the pymc overview notebook: https://docs.pymc.io/en/latest/learn/core_notebooks/pymc_overview.html. It has alrrady been ported to v4 and as part of the versioned docs it is executed automatically every time we build the docs. We forgot to close this issue though, doing it now
