Quick Start
-----------

In order to use this library, you first need to go through the following steps:

1. `Select or create a Cloud Platform project.`_
2. `Enable the trace API.`_
3. `Setup Authentication.`_

.. _Select or create a Cloud Platform project.: https://console.cloud.google.com/project
.. _Enable the trace API.:  https://cloud.google.com/trace
.. _Setup Authentication.: https://googleapis.github.io/google-cloud-python/latest/core/auth.html

Installation
~~~~~~~~~~~~

Install this library in a `virtualenv`_ using pip. `virtualenv`_ is a tool to
create isolated Python environments. The basic problem it addresses is one of
dependencies and versions, and indirectly permissions.

With `virtualenv`_, it's possible to install this library without needing
system install permissions, and without clashing with the installed system
dependencies.

For more information on setting up your Python development environment,
such as installing ``pip`` and ``virtualenv`` on your system, please refer
to `Python Development Environment Setup Guide`_ for Google Cloud Platform.
