+3 Ways to Create an Alchemical Network
+--------------------------------------
+
+1. Python API 
+^^^^^^^^^^^^^
+
+You can manually create a :class:`.AlchemicalNetwork` by creating a list
+of :class:`.Transformation` objects. For examples using the Python API,
+see :ref:`cookbook on creating alchemical networks <cookbook/create_alchemical_network.nblink>`.
+
+2. Python ``NetworkPlanner`` Convenience Classes
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+OpenFE also provides the convenience classes :class:`.RBFEAlchemicalNetworkPlanner` and :class:`.RHFEAlchemicalNetworkPlanner`,
+which use the :class:`.RelativeHybridTopologyProtocol` for creating AlchemicalNetworks. For examples using these convenience classes, see :ref:`Relative Alchemical Network Planners cookbook <cookbook/rfe_alchemical_planners.nblink>`.
+
+.. note::
+   The Network Planners are provided for user convenience. While they cover
+   majority of use cases, they may not currently offer the complete range
+   of options available through the Python API.
+
+3. Command Line ``NetworkPlanner`` 
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+The Alchemical Network Planners can also be called directly from the 
+:ref:`command line interface <userguide_cli_interface>`.
+
+For example, you can create a Relative Hydration Free Energy (RHFE) network
+using:
+
+.. code:: bash
+
+    $ openfe plan-rhfe-network -M dir_with_sdfs/
 
+or a Relative Binding Free Energy (RBFE) network using:

 Chemical Systems
 ----------------
 
-In order to define the input systems to a Protocol,
-which correspond as the end states of an alchemical transformation,
-we need an object model to represent their chemical composition.
-In ``openfe`` a :class:`.ChemicalSystem` is used to capture this information,
-and represents the chemical models that are present in each end state.
+A :class:`.ChemicalSystem` represents the end state of an alchemical transformation,
+which can then be input to a :class:`.Protocol`. 
 
-A :class:`.ChemicalSystem` **does** include information, where present, on:
+A :class:`.ChemicalSystem` *does* contain the following information (when present):
 
 * exact atomic information (including protonation state) of protein, ligands, co-factors, and any crystallographic

 Components
 ----------
 
-A :class:`.ChemicalSystem` is composed of many :class:`.Component` objects,
-each representing a single ''piece'' of the overall system.
+A :class:`.ChemicalSystem` is composed of many 'component' objects, which together define overall system.

 Examples of components include:

-* :class:`.SmallMoleculeComponent` to represent ligands and cofactors
-* :class:`.SolventComponent` to represent the solvent conditions
+* :class:`.ProteinComponent`: an entire biological assembly, typically the contents of a PDB file.
+* :class:`.SmallMoleculeComponent`: typically ligands and cofactors
+* :class:`.SolventComponent`: solvent conditions
 
 Splitting the total system into components serves three purposes:
 
-* alchemical transformations can be easily understood by comparing the differences in Components
-* components can be reused to compose different systems
-* ``Protocol`` \s can treat different components differently, for example applying different force fields
+1. alchemical transformations can be easily understood by comparing the differences in components.
+2. components can be reused to compose different systems.
+3. :class:`.Protocol`\s can have component-specific behavior. E.g. different force fields for each component.
 
 Thermodynamic Cycles
 --------------------
 
-With a language to express chemical systems piecewise, we can now also construct thermodynamic cycles based on these.
+We can now describe a thermodynamic cycle as a set of :class:`.ChemicalSystem`\s. 
 The exact end states to construct are detailed in the :ref:`pages for each specific Protocol <userguide_protocols>`.
-For example to  construct the classic relative binding free energy cycle, we will need four components, two ligands,
-a protein, and a solvent.  These four ingredients can then be combined into the four points on the thermodynamic cycle
