    "# GSP SEVT NETCONF/YANG\n",
    "\n",
    "This notebook goes through a set of examples with a XRv9000 virtual platform. The goal is to show how NETCONF/YANG can be simply leveraged with IOS-XR to perform a range of tasks for the customer. We will cover topics like:\n",
    "\n",
    "* Basic connectivity\n",
    "* Why we really want to use some form of client library\n",
    "* Getting started with a Python client like [ncclient](https://github/com/ncclient/ncclient)\n",
    "* Model and feature discovery\n",
    "* Querying and configuring features\n",
    "\n",
    "First, let's talk a little about the environment being used here. This is all run inside **jupyter notebooks**, which some may already be familiar with as **iPython notebooks**.\n",
    "\n",
    "A jupyter notebook lets us mix text and code and provides a simple way to experiment with Python code.\n",
    "\n",
    "## Useful Snippets\n",
    "\n",
    "Let's define some useful little snippets of code that we might want to run to define utilities or to enable debugs, set variables for use, etc.\n",
    "\n",
    "### Enable Debugging\n",
    "\n",
    "The ncclient libary can generate vast amounts of debug information via standard Python logging. The code fragment below shows how to enable this. But the logging is **vast**! You have been warned!"
