+Interactive Path Analysis Client (IPA)
+====================================================
+
+The interactive path analysis (IPA) client connects to VPR's server mode and allows interactive visualization of timing paths and their placement and routing. This client application is called **IPAClient** and can also be used to test VPR's server mode functionality. It is available in a public Git repository:  
+`https://github.com/w0lek/IPAClient <https://github.com/w0lek/IPAClient>`_.
+
+This UI application is designed to generate requests for VPR in server mode and display the responses in a readable format, acting as a result viewer.
+
+More details on how to build and use **IPAClient** can be found in the `README <https://github.com/w0lek/IPAClient/blob/main/README.md>`_.
