Contribution to the documentation

I am a beginner to open source contributions and I wanted to contribute to pytorch like in the website a little tweaking to the documentation(minor changes).
I tried looking for the same (the text in the website) in github of pytorch but couldn’t find the file for it.
I’d like to fork it for changes.
is there anyone who can help me with it?

As a starting point I would recommend to check the Contributing Guide as well as this doc.
Once you are familiar with the build process etc. you could then create an issue on GitHub and discuss the proposed changes.
For your current request: which file/docs would you like to change?
