 For the ``desktop-based`` application, it is optimized on ``Windows 10`` and ``macOS Big Sur``. ``Ubuntu 18.04.5`` is also tested. For ``Linux`` operating system version below ``Ubuntu 18.04.5`` or equivalent, such as ``Ubuntu 16.04``, ``PyQtWebEngine`` may not work properly. For other versions of operating systems, the ``desktop-based`` application may still work, however, the **layout** of the application may differ.
 
-For the ``web browser-based`` version, we suggest running in ``Linux`` or ``macOS`` environment. If users want to run on ``Windows`` systems, ``Windows 10`` or above is recommended. Users can also use ``docker`` to run the ``web browser-based`` version. However, ``WSL`` is needed to run the docker version on ``Windows 10`` or above.

+
+* pull and run the docker image:
+    ```
+    docker pull rickyma1/pangraphviewerweb
+    docker run -d -P --name pangraph1 rickyma1/pangraphviewerweb > /dev/null
+    ```
+* find the published port:
+    ```
+    docker port pangraph1 8000
+    ```
+3. If the IP address of the machine is 1.2.3.4 (local machine IP address is ``127.0.0.1`` or ``locallhost``), and the published port is 8000, then the url to open the program is:
+    ```
