Must have installed the following dependencies:

Go to Discord Developer Portal.
Create a New Application.
Name it whatever you want.
Go to the BOT settings tab.
Click on Add A Bot.
Go back to the General Information settings tab.
Click on Copy ID.
Go to any Discord Permissions Calculator.
Paste your ID in the Client ID box.
Select/Check the Manage Channels permission.
Copy the link formed and open it in another window.
Select the server you would like to nuke.
Click on the Authorize button.
Verify that you are not a robot by checking the verification box.
Once it says Authorized, it means that the bot is now in the server you selected.
Now, head back to the Discord Developer Portal.
Select the application which you just created.
Go the BOT settings tab again.
Click on Copy button under the Token menu.
Create a json file named config.json in your cloned project directory.
The config.json file should look like this:

{
  "BOT_TOKEN" : "paste the token youy copied here (inside the quotes)"
}

Once you have created the config.json file and followed all the steps correctly, you can just start the main.py file by writing following command in your terminal:

python main.py

After running the file, you should see something like this.
Now, you can select a speed for the nuke bot. Recommended Speed = Medium.
Once you have selected a speed, it will take about 4-5 seconds for the bot to login (depends on your internet speed).
After the bot logs in, you can keep looking at the console for all the real-time updates.
Also, if the script shows a RunTimeError, and exits with exit code 0, it means that the bot had access to 0 channels.
