Step-by-step guide for setup

My apologies if this exists, but I have not been able to find it.

Is there a step-by-step guide for setting up a keybase.io account? I've been trying to work remotely with someone who is non-technical, and it has been very challenging, since screens change what they look like after you get to different stages/steps of setting the account up.

Any assistance is greatly appreciated.

The issue requests a step-by-step guide for setting up a keybase.io account, including the changing screens encountered during setup. Start by reviewing the repository's existing client, installer, and website guidance, then define the supported setup path and the screenshots or steps needed for a non-technical user. Done means the guide covers the setup process clearly from start to finish.
