Hi there:wave: I would like to work on your login screen. Would you want me to do the UI only, or the logic as well for the authentication?

@alistairholmes Welcome to ChatAir. For the Oct 1 Sprint, we're looking to get UI done. Please feel free to get started. You may first wanna read the contribution guidelines in the README.
You'll be able to find the design for login screen within the designs folder.
