How to fork the repo and use it.

Create 3 groups
One person from each group will fork the repo.
- If you don't have a github account, create one.
- Go to the repo page and click on the Fork button on the top right corner. (This will create a copy of the repo in your account)
- Add members to the group as collaborators.
  - Go to the repo page in your account.
  - Click on Settings tab.
  - Click on Collaborators on the left side.
  - Add the other members in the group as collaborators.
Clone the repo to your local machine.
- create a key pair
```
 ssh-keygen -t rsa -b 4096 -C 
```
- copy the public key to your github account
```
 cat ~/.ssh/id_rsa.pub
```
- Go to settings>SSH and GPG keys> New SSH key and paste the key.
- Clone the repo
```
 git clone <repo_url>
```
