Felipe Monteiro d80aa0bd8f docs: Update getting started documentation
Currently the getting started documentation is somewhat incorrect:
usage of pip3 install is not necessary as "regular" usage of
pegleg entails using ./tools/pegleg.sh which uses the Pegleg
Docker image.

Also, the CLI guide doesn't include any useful examples so some
have been added.

What is Pegleg?
---------------
Pegleg is a document aggregator that will aggregate all the documents in a
repository and pack them into a single YAML file. This allows for operators to
structure their site definitions in a maintainable directory layout, while
providing them with the automation and tooling needed to aggregate, lint, and
render those documents for deployment.
For more information on the documents that Pegleg works on see `Document Fundamentals`_.
Basic Usage
-----------
Before using Pegleg, you must:
1. Clone the Pegleg repository:
.. code-block:: console
git clone https://git.airshipit.org/airship-pegleg
2. Install `Docker CE`_, as Pegleg relies on it for CLI execution.
3. Clone the repos containing your `site definition libraries`_ into the
local filesystem where Pegleg is running, as Pegleg can only work with files
available in the local directory.
You will then be able to use all of Pegleg's features through the CLI. See CLI_ for more
information.
