 - Semi-Interacting Massive Bodies - Gravitationally affect and are affected by fully-interacting massive bodies, do not gravitationally affect and are not affected by other semi-interacting massive bodies.
 - Test Particles - Gravitationally affected by fully-interacting massive bodies only. 
 
-To generate the initial conditions, run the Python script titled **initial_conditions.py**. To process the output file, run the script titled **output_reader.py**. 
+To generate the initial conditions, run the Python script titled **initial_conditions.py**. This script also runs Swiftest SyMBA, generating output. To process the output file, run the script titled **output_reader.py**. 
 
 **Chambers2013**
 
-This example acts as a comparison to the work of [Chambers 2013](https://www.sciencedirect.com/science/article/pii/S0019103513000754?via%3Dihub). It can be found in the ```/swiftest/examples/Chambers2013``` directory. It is intended to be run using the SyMBA integrator.

It can be found in the ```/swiftest/examples/Chambers2013``` directory. It is intended to be run using the SyMBA integrator and highlights how to run Swiftest using and executable, as opposed to through a Python script. To generate the initial conditions, run **init_cond.py**. To run Swiftest with these intial conditions, type:
+
+```
+./swiftest_driver symba param.in

+To process the output file, run the script titled **<span>scattermovie.py</span>**.
 
 **Fragmentation**
 
 This example highlights the functionality of the Fraggle algorithm. It can be found in the ```/swiftest/examples/Fragmentation``` directory. It is intended to be run using the SyMBA integrator. It contains three pre-built collisional test cases:
 
-- A Head-On Disruptive Collision
-- An Off-Axis Supercatastrophic Disruptive Collision
+- A Head-On Disruptive Collision 
+- An Off-Axis Super-Catastrophic Disruptive Collision
 - A Disruptive Hit and Run Collision
 
-To generate a movide depicting the collision and results of each test case, run the Python script titled **Fragmentation_Movie.py**.
+To generate a movie depicting the collision and results of each of the test cases, run the Python script titled **Fragmentation_Movie.py**.
 
 **helio_gr_test**
 
-This example demonstrates the functionality of general relativity in Swiftest HELIO. It can be found in the ```/swiftest/examples/helio_gr_test``` directory. It is intended to be run using the HELIO integrator. Because the SyMBA integrator is built upon the HELIO integrator, GR can also be used in SyMBA.
