Thanks for the correct URL.

It's not worth my being a stickler about this time but in the future @vpzee please do not make various other formatting changes in a pull request that has nothing to do with them.

Thanks for fixing this link! 🍰

This was my first contribution ever. I can use every guidance I can get to be a good citizen here.
Thank you.

Congrats @vpzee! To be as explicit as possible: if you're fixing a bug in a project, just fix the bug. Don't fix anything else in that pull request unless the project owner or maintainer ask you to. It makes reviewing the changes/fixes much easier for us and will improve your pull request's chances of being merged.
