Polish README to help new contributors

[sanjana2505006]

The current README.md for LinuxDroid is very informative, but it can be improved to make it more structured, readable, and user-friendly. A well organized README will help new users understand the project quickly, find installation instructions easily, and encourage contributions.

Hello @AryanVBW 👋
I’d love to work on improving the README for better readability and structure and could you please add labels like documentation and hacktoberfest?
