	- The data will be saved in a `JSON` file named `db.json` for further reference
	- Every entry will have a time limit after which it will be updated (Data expires after 7 days)

	## Setup instructions

	Download the required packages from the following command in you terminal.(Make sure you're in the same project directory)

	```
	pip3 install -r requirements.txt
	```
