Issue:
Workflow versions #141 into dev
Two PR's may seem a little redundant. However, this addition was focused on the tests performed with PRs so it was important to test that out on the issue branch prior to the PR into dev. 
Workflow versions are out of date
Under each of the github workflow files: `gh_pages.yml`, `publish-to-pypi.yaml`, and `tests.yml` all refer to @v2 for *checkout* and *setup-python*.  They versions should be updated to v4 to avoid workflow complications for different users.

+Overview
+--------
+The ``ProjectManager`` is the primary system for interacting with ORBIT to simulate
+a wind project. Users can customize their project by specifying a a wide variety of
+parameters as a dictionary (see tutorial: :ref:`Project Manager Tutorial <project_manager>`).
+For more details of the code implementation, please see :doc:`Project Manager API <api_ProjectManager>`.
+
+It instantiates a class aggregates project parameters, specifies a start date, and interprets a weather
+profile, and it employs a collection of decorators, `methods`, and `classmethods` to run the simulation.
+Among these methods are `design_phases` and `install_phases` that serve as components to the simulation.
+Additionally, some methods search and catch key errors to avoid simulation issues, export progress logs,
+and save the outputs.
+
+Run
+---
+This method checks to see if a design or install phase is instatiated prior to running them. Depending on
+which design phases are specified, each phase is run in no particular order and the results are added to
+`.design_results` dictionary. Conversely, the install phases can be run sequentially or as overlapped
+processes (see example: :ref:`Overlapping install <project_manager>`). It is worth noting, that ORBIT
+has built in logic to determine any dependency between install phases.
+
+Properties
+----------
+The `@property` decorators allow the ``ProjectManager`` to access and manipulate the attributes of certain classes. Of the
+several properties some important ones are:
+
+.. toctree::
+    :maxdepth: 2
+    :caption: Contents:
+
+- capex_categories: CapEx Categories
+- npv: Net Present Value
+
+Finally, these attributes are collected in an `output` dictionary.

+
+    ORBIT does not specify a dollar-year when calculating BOS cost and it does

 Evaluating BOS costs is complicated by the large number of design choices for
 each component, the impact of weather delays on the installation processes, the
 challenge of transporting and hoisting large components at sea, the variation
