-
-
-    2. Install opencv, autopy, pynput, pyfakewebcam library:
-
-            $ sudo pip3 install opencv-python
-            $ sudo pip3 install autopy
-            $ sudo pip3 install pynput
-            $ sudo pip3 install pyfakewebcam
-
-
-    3. FFmpeg and v4l2loopback Setup (for virtual device creation and video frames rendering):
-
-        a. Install FFmpeg by typing following command:
-
-                $ sudo apt install ffmpeg
-
-
-        b. Install v4l2loopback-dkms v4l2loopback-utils module:
-
-                $ sudo apt install v4l2loopback-dkms v4l2loopback-utils
-                $ sudo modprobe -r v4l2loopback
-                $ sudo depmod -a
-
-
-## Running the application (Strictly follow the below order inorder to run it successfully):
-
-    1. Creating virtual device (for webcam) and server On Desktop / Laptop side:
-
-        a. Create device using below 2 commands:
-                $ sudo modprobe v4l2loopback devices=1 video_nr=20 card_label='Wireless-X Camera' exclusive_caps=1
-
-
-            Check if your virtual device is created
-                $ ls /dev | grep -P '^video\d+$'
-
-            (Optional if already done earlier):
-                $ sudo depmod -a
-
-
-        b. run python file in the directory using below command:
-                $ python3 Wireless-X_server.py
-            
-            If no errors encountered, below output should be displayed on terminal:
-
-                    ---------Wireless-X Server------
-                    Camera stream port: 9998
-                    Keyboard and Mouse Listening port: 6666
-
-                    
-
-    2. Application Installation and Setup on Android Smartphone:
-
-        a. Install the Wireless-X apk on Android smartphone and give required permissions.
-
-        b. Now enter the IP address of the Laptop/ Desktop on which the server is hosted. You can type the below command in terminal to get host IP:
-                $ ifconfig 
-        
-        c. Click on Test Button to test the connection of smartphone with the server. If failed, Recheck if you have entered correct IP address of Laptop/ Desktop (on 
-            which the server is running).
-
-        d. After successfull connection, you would be able to control mouse, keyboard of laptop and use smartphones camera as webcam for the laptop/Desktop.
-
-        e. Now you would be able to use this virtual webcam device on chrome for video conferincing. (Tested on chrome for MS Teams and Google Meet).
-
-        f. (Optional) Inorder to test if camera frames are received to the Laptop/ Desktop, use the below command while (Note: camera option should be turned on in the 
-            Wireless-X apk on Android):
-                $ ffplay /dev/video20 
-
-
-## IMPORTANT: Make sure you have a virtual device created before running the Wireless-X_server.py.
-
-
-
-
-#### *Extra (Inorder to remove v42loopback devices, use below command):
-            
-            $ sudo modprobe -r v4l2loopback
-
-
-
-
-## Steps for Debugging (If python code doesn't run after above commands):
-
-    1. Check if your virtual device is created
-
-        $ ls /dev | grep -P '^video\d+$'
-        OR
-        $ v4l2-ctl --list-devices    # TO List the virtual devices in detail
-
-            Output should look somewhat like this:
-
-                Wireless-X Camera (platform:v4l2loopback-000):
-                    /dev/video20
-
-                Webcam C170: Webcam C170 (usb-0000:00:1a.0-1.2):
-                    /dev/video0
-                    /dev/video1
-
-
-    2. Inorder to test if virtual device is working:
-        Copy the sample code from  https://github.com/jremmons/pyfakewebcam page and save it as python file and run it.
-            
-            $ python3 demo.py
-
-        If everything worked correctly, no error should be displayed and terminal should be blank.
-        Now, Open another terminal and test if virtual device output is being display by entering below command:
-            
-            $ ffplay /dev/video20
-        
-        Note: ffplay
