 This is the go implementation of ArozOS (aka ArOZ Online) Web Desktop environment,designed to run on linux, but somehow still works on Windows and Mac OS
 
+
+
+This README file is intended for developer only. If you are normal users, please refer to the README file outside of the /src folder. 
+
 ## Development Notes
 
 - Start each module with {ModuleName}Init() function, e.g. ```WiFiInit()```
-- Put your function in module (if possible) and call it in the main program
+- Put your function in mod (if possible) and call it in the main program
 - Do not change the sequence in the startup() function unless necessary
 - When in doubt, add startup flags (and use startup flag to disable experimental functions on startup)
 
+## File System Virtualization and File System Abstractions Layers
+
+The ArozOS system contains both the virtualization layer and abstraction layer. The easiest way to check if your path is under which layer is by looking at their starting dir name.

+| --------------------------------------------- | ---------------------------------------------------- | ------------------------------------------------ |

+| fsh (*File System Handler) + subpath (string) | fsh (localfs) + /files/users/alan/Desktop/myfile.txt | File System Abstraction                          |
+| {physical_location}/{subpath}                 | /home/aroz/arozos/files/users/Desktop/myfile.txt     | Physical (Disk) Layer                            |
+
+Since ArozOS v2.000, we added File System Abstraction (fsa, or sometime as seen as fshAbs, abbr for "File System Handler underlaying File System Abstraction) to the (already complex) File System Handler (fsh) infrastruture.  There are two type of fsh that are currently supported by ArozOS File System Abstraction layer.
+
+
+
 ## ArOZ JavaScript Gateway Interface / Plugin Loader
+
 The ArOZ AJGI / AGI interface provide a JavaScript programmable interface for ArozOS users to create 
 plugin for the system. To initiate the module, you can place a "init.agi" file in the web directory of the module
 (also named the module root). See more details in the [AJGI Documentation](AJGI Documentation.md).
 
 ## Subservice Logics and Configuration
+
 To intergrate other binary based web server to the subservice interface,
 you can create a folder inside the "./subservice/your_service" where your binary
 executable should be named identically with the containing directory.

 ### Subservice Exec Settings
+
 In default, subservice routine will create a reverse proxy with URL rewrite build in that serve your web ui launched
 from the binary executable. If you do not need a reverse proxy connection, want a custom launch script or else, you can 
 use the following setting files.
 
 ```
-.noproxy		=> Do not start a proxy to the given port
-.startscript	=> Send the launch parameter to the "start.bat" or "start.sh" file instead of the binary executable
-.disabled		=> Do not load this subservice during startup. But the user can enable it via the setting interface
+.noproxy        => Do not start a proxy to the given port
+.startscript    => Send the launch parameter to the "start.bat" or "start.sh" file instead of the binary executable
+.disabled        => Do not load this subservice during startup. But the user can enable it via the setting interface
 ```
 
 Here is an example "start.bat" used in integrating Syncthing into ArOZ Online System with ".startscript" file placed next
 to the syncthing.exe file.
+
 ```
 if not exist ".\config" mkdir ".\config"
 syncthing.exe -home=".\config" -no-browser -gui-address=127.0.0.1%2
 ```
 
 ## Systemd support
+
 To enable systemd in your host that support aroz online system, create a bash script at your aroz online root named "start.sh"
 and fill it up with your prefered startup paratmers. The most basic one is as follow:
 
 ```
 #/bin/bash
 sudo ./aroz_online_linux_amd64
-
 ```
 
 And then you can create a new file called "arozos.service" in /etc/systemd/system with the following contents (Assume your aroz online root is at /home/pi/arozos)
