Add info on how to use the repo in readme

[krishna-mundada]

I've recently come across this repo and wanted to use it.

I've had to struggle to figure out how to use it at all. Please add info to read me including things like installation, usage, examples etc

Sure. I will add a file on how to set up this repo. But remind you that this repo is only the frontend codebase of the Animechan project. Backend codebase is private.
