+Running ARTEMIS
+===============
 
-Coming soon!
+This document demonstrates a few examples of how to **run ARTEMIS** after installation and compilation. Example input scripts reside in the ``Examples/`` directory.
+
+1. Simple Testcase without LLG
+------------------------------
+
+Below is an air-filled X-band rectangular waveguide simulation.
+
+- **MPI + OpenMP Build**:
+
+  .. code-block:: bash
+
+     make -j 4 USE_LLG=FALSE
+     mpirun -n 4 ./main3d.gnu.TPROF.MTMPI.OMP.GPUCLOCK.ex Examples/Waveguide/inputs_3d_empty_X_band
+
+- **MPI + CUDA Build**:
+
+  .. code-block:: bash
+
+     make -j 4 USE_LLG=FALSE USE_GPU=TRUE
+     mpirun -n 4 ./main3d.gnu.TPROF.MTMPI.CUDA.GPUCLOCK.ex Examples/Waveguide/inputs_3d_empty_X_band
+
+2. Simple Testcase with LLG
+---------------------------
+
+Below is a magnetically tunable X-band filter simulation.
+
+- **MPI + OpenMP Build**:
+
+  .. code-block:: bash
+
+     make -j 4 USE_LLG=TRUE
+     mpirun -n 8 ./main3d.gnu.TPROF.MTMPI.OMP.GPUCLOCK.ex Examples/Waveguide/inputs_3d_LLG_filter
+
+- **MPI + CUDA Build**:
+
+  .. code-block:: bash
+
+     make -j 4 USE_LLG=TRUE USE_GPU=TRUE
+     mpirun -n 8 ./main3d.gnu.TPROF.MTMPI.CUDA.GPUCLOCK.ex Examples/Waveguide/inputs_3d_LLG_filter
