sphinx: import docs

The Yocto Project docs was migrated from Docbook to Sphinx in YP
 3.2. This 3.1 is an LTS release, and since 3.1 docs are 'close to'
 the docs in 3.2, we agreed to backport sphinx docs onto 3.1.

This first patch brings all changes done in 3.2 until:
7f64574f7 README: include detailed information about sphinx

There are other changes after this commit, but they will be
 selectively backported in individual patches.

This patch was generated with the following command:

git cherry-pick -n \
 $(git log --reverse --oneline \
 ac352ad7f95db7eeacb53c2778caa31800bd7c26..7f64574f7 \
| cut -f1 -d' ')

The following commits were applies in the dunfell docs, but not in
master, so they were first reverted (and squashed into this change). A
commit will reintroduce the content from these patches in the Sphinx
files in a followup patch.

069c27574 Documenation: Prepared for the 3.1.1 release
bd140f0f9 Documentation: Add 3.1.1 version updates missing from previous commit

+Preparing to Use Toaster
+************************
+
+This chapter describes how you need to prepare your system in order to
+use Toaster.
+
+.. _toaster-setting-up-the-basic-system-requirements:
+
+Setting Up the Basic System Requirements
+========================================
+
+Before you can use Toaster, you need to first set up your build system
+to run the Yocto Project. To do this, follow the instructions in the
+":ref:`dev-manual/dev-manual-start:preparing the build host`" section of
+the Yocto Project Development Tasks Manual. For Ubuntu/Debian, you might
+also need to do an additional install of pip3. ::
+
+   $ sudo apt-get install python3-pip
+
+.. _toaster-establishing-toaster-system-dependencies:
+
+Establishing Toaster System Dependencies
+========================================
+
+Toaster requires extra Python dependencies in order to run. A Toaster
+requirements file named ``toaster-requirements.txt`` defines the Python
+dependencies. The requirements file is located in the ``bitbake``
+directory, which is located in the root directory of the
+:term:`Source Directory` (e.g.
+``poky/bitbake/toaster-requirements.txt``). The dependencies appear in a
+``pip``, install-compatible format.
+
+.. _toaster-load-packages:
+
+Install Toaster Packages
+------------------------
+
+You need to install the packages that Toaster requires. Use this
+command::
+
+   $ pip3 install --user -r bitbake/toaster-requirements.txt
+
+The previous command installs the necessary Toaster modules into a local
+python 3 cache in your ``$HOME`` directory. The caches is actually
+located in ``$HOME/.local``. To see what packages have been installed
+into your ``$HOME`` directory, do the following::
+
+   $ pip3 list installed --local
+
+If you need to remove something, the following works::
+
+   $ pip3 uninstall PackageNameToUninstall
