Quickstart
Note
First, ensure you have TextMeshPro in your project. This usually comes by default on modern versions of Unity. If you do not have it, navigate to the Package Manager and install the latest version.
To check out a simple demo application showing some features of what can be done, open the demo scene found at Assets/Llama Software/Scenes/Demo
To check out the Components Overview, open the demo scene found at Assets/Llama Software/Scenes/UI Overview (you can get here by clicking Element Overview in the first scene as well).
That should be it! Play with the UI, check out the components, and familiarize yourself with the inspectors. If you want to read more about each component, you can start on the Component Overview
