How to set up and run the bot locally

Setup

Install Python 3.8 from https://www.python.org/downloads/
When you're at the installer part, tick the PATH box.
Open Command Prompt from Windows, navigate to the directory using cd
For example, if your source code is in Desktop, you will need to cd desktop and cd {filename} before.
Execute pip install -r requirements.txt (without the quotation mark)

Go to Discord's Developer Portal at https://discord.com/developers/applications
Create an application if you haven't already, and navigate into it.
On the settings bar at the side, you will see a Bot section, go to it and Build-A-Bot.
After you're done building a Bot, name the bot and give it a profile picture.
Reveal the token by clicking on it, then copy and replace the bot_token onto authentication.yml
Under Privileged Gateway Intents, toggle on Server Members Intent (THIS is very important!)

In the same application in the Discord's Developer Portal, head to the OAuth2 section on the side.
Under the Scopes, tick on Bot, another section below should appear, tick on Administrator, or whatever permissions you need.
Copy the link generated in the middle, this is the invite link for your bot, just like how you used to invite other bots.

In the same command prompt window from earlier where you executed pip install -r requirements txt, execute python3 main.py
The bot should be successfully running and you will see a bunch of lines saying the bot has started.
