Matching hardware and software stack distinction in the docs

 Identifying a Similar System
 ------------------------------
 
-The easiest place to start when configuring a new system is to find the closest similar
-one that has an existing configuration already. Existing system configurations are listed
-in the table in :doc:`system-list`.
+To specify a new system, we recommend to identify a system in Benchpark with the most similar
+hardware. We list specified Benchpark Systems in the System Specifications Catalogue in :doc:`system-list`.
 
 If you are running on a system with an accelerator, find an existing system with the same accelerator vendor,
 and then secondarily, if you can, match the actual accererator.

 For example, if your system has an NVIDIA A100 GPU and an Intel x86 Icelake CPUs, a similar config would share the A100 GPU, and CPU architecture may or may not match.
 Or, if I do not have GPUs and instead have SapphireRapids CPUs, the closest match would be another system with x86_64, Xeon Platinum, SapphireRapids.
 
-If there is not an exact match that is okay, steps for customizing are provided below.
+If there is not an exact match, you may add a new directory in the `systems/all_system_definitions` where you will describe the hardware on your system.  Please name it following the naming convention::
+
+  [INTEGRATOR]-MICROARCHITECTURE[-GPU][-NETWORK]
+
+where::
+
+  INTEGRATOR = COMPANY[_PRODUCTNAME][...]
+
+  MICROARCHITECTURE = CPU Microarchitecture
+
+  GPU = GPU Product Name
+
+  NETWORK = Network Product Name
+
+Please follow the yaml format from existing system specifications in `systems/all_system_definitions`.

+New System software stack definition
+------------------------------
+``system.py`` in Benchpark provides an API to represent a system software stack as a 
+command line parameterizable object.  
+If none of the available software stack specifications match your system, 
+you may add a new directory in the `systems` directory following the naming convention::
+
+  SITE-SYSTEMNAME
+
+where::
+
+  SITE = nosite | DATACENTERNAME

-If you want to add support for a new system you can add a class definition
-for that system in a separate directory in ``systems/``.
-The best way is to copy the system.py for the most similar system identified above, and then paste it in a new directory and update it.
+Next, copy the system.py for the most similar system identified above into this new directory,
