You should look into which-key, which is a popup showing active key bindings in the active context. And maybe start with a configuration-pack like doom-emacs or spacemacs, as they have good support for the vim-bindings, as also come with which-key pre-configured. And as I remember, they also allow deactivating vim-bindings if you want the pure Emacs-experience.
