 3 | A simple rickroll detector
 4 | # Installation 
 5 | This isn't a python module on pypi as of now so you'll need to download the rickroll_detector.py file and keep it in the same directory as your main file. <br> <br>
 6 | You can also `git clone https://github.com/CodeWithSwastik/rickroll-detector`
 7 | # Usage 
 8 | 
 9 | ```python
10 | from rickroll_detector import find_rickroll
11 | 
12 | result = find_rickroll("https://youtu.be/oHg5SJYRHA0")
13 | print(result) #returns True
14 | ```
15 | 
16 | # Async Usage 
17 | ```python
18 | from async_rickroll_detector import RickRollDetector
19 | 
20 | detector = RickRollDetector()
21 | await detector.find('https://youtu.be/oHg5SJYRHA0')
22 | ```
23 | 
24 | # Example bot
25 | I also have a bot.py file here which is an example discord bot that will detect rickrolls
