 # Recipes
-`flowerMD` offers the following two ready-to-go recipes to illustrate how the design creates
-potential for expanding the library of open-source and version-controlled workflows. The example code included in this repository demonstrates how the modularity of `flowerMD`
-allows use and re-use of workflows, using pre-built "recipe steps" (subclasses) included in
-the repository:
-`flowerMD.modules.welding.SlabSimulation`, `flowerMD.modules.welding.Interface`, `flowerMD.modules.welding.WeldSimulation`,
+The modular design of `flowerMD` creates potential for expanding a library of open-source and version-controlled workflows. To illustrate this, `flowerMD` offers the built-in polymer welding recipe using the following subclasses:`flowerMD.modules.welding.SlabSimulation`, `flowerMD.modules.welding.Interface`, `flowerMD.modules.welding.WeldSimulation`,
 and `flowerMD.library.simulations.Tensile`.
 
-We can use these four blocks to build the following recipe:
-1. `SlabSimulation` creates two "slabs" of e.g. polyethylene
-2. `Interface` joins two resultant slabs at an interface
-3. `WeldSimulation` simulates thermal welding at this interface, and
+Combined, these four subclasses create the polymer welding recipe:
+
+1. `SlabSimulation` creates one "slab" with two flat surfaces of e.g. polyethylene.
+2. `Interface` duplicates the resultant slab and creates an "interface" system.
+3. `WeldSimulation` simulates thermal welding at this interface.
 4. `Tensile` simulates a tensile test of the resultant weld to create a stress/strain curve.
 
-Note that each of these steps can be run independently, and each simulation
-type is agnostic to system and force field selection, enabling easy iteration with different
-materials, force fields, etc. without replicating the workflow code itself. One example might be that we could instead run `SlabSimulation` on two different bulk polymers, then reuse the rest of the recipe unchanged. We could also iterate over new weld temperatures pending results of `Tensile` runs, etc.
+Note that each of these steps can be run independently. For example, from the output of a single slab simulation, we could iterate over several weld temperatures where each one is followed by a series of tensile runs with different strain rates.
