.. inclusion-intro

The National Renewable Energy Laboratory Wind Analysis Library (NRWAL):

#. A library of offshore wind cost equations (plus new energy technologies like marine hydro!)
#. Easy equation manipulation without editing source code
#. Full continental-scale integration with the NREL Renewable Energy Potential Model (reV)
#. Ready-to-use configs for basic users
#. Dynamic python tools for intuitive equation handling
#. One seriously badass sea unicorn

To get started with NRWAL, check out the `NRWAL Config documentation
<https://nrel.github.io/NRWAL/NRWAL/NRWAL.config.config.html>`_ or the
`NRWAL example notebook <https://github.com/NREL/NRWAL/blob/main/examples/example.ipynb>`_.
You can also launch the notebook in an interactive jupyter shell
right in your browser without any downloads or software using
`binder <https://mybinder.org/v2/gh/NREL/NRWAL/HEAD>`_.

Here is the important stuff:

 - `The NRWAL Equation Library <https://github.com/NREL/NRWAL/tree/main/NRWAL/analysis_library>`_.
 - `Default NRWAL Configs <https://github.com/NREL/NRWAL/tree/main/NRWAL/default_configs>`_.

Installing NRWAL
================

Option 1: Install from PIP or Conda (recommended for analysts):
---------------------------------------------------------------

1. Create a new environment:
    ``conda create --name nrwal``

2. Activate directory:
    ``conda activate nrwal``

3. Install reVX:
    1) ``pip install NREL-NRWAL`` or
    2) ``conda install nrel-nrwal --channel=nrel``

Option 2: Clone repo (recommended for developers)
-------------------------------------------------

1. from home dir, ``git clone https://github.com/NREL/NRWAL.git``
    1) enter github username
    2) enter github password

2. Create ``NRWAL`` environment and install package
    1) Create a conda env: ``conda create -n nrwal``
    2) Run the command: ``conda activate nrwal``
    3) cd into the repo cloned in 1.
    4) prior to running ``pip`` below, make sure the branch is correct (install
       from master!)
    5) Install ``NRWAL`` and its dependencies by running:
       ``pip install .`` (or ``pip install -e .`` if running a dev branch
       or working on the source code)
