Describe the bug
For contribution we should make the commit to our forked repository then make the PR from there to the main repo.
The command here is

git clone https://github.com/reflex-dev/reflex.git

to clone the repo, which is not correct.

Expected behavior
A clear and concise description of what you expected to happen.

git clone https://github.com/<YOUR-USERNAME>/reflex.git
