Others can also pull the changes you make in your version.

2. To download the content to your computer, type the following in a terminal

git clone https://github.com/raghurama123/DataScience.git

or click the 'code' botton above and then click 'Download zip'

If you also Fork the material, then replace 'raghurama123' in the above line with your 'username'

3. If you want to try the material in a web browser, i.e., to test the code or make small changes and run the code, you can access this repository at the interactive platform Binder by clicking the link: https://mybinder.org/v2/gh/raghurama123/DataScience/HEAD

If you also Fork the material, then replace 'raghurama123' in the above line with your 'username'
