Getting Started

Get Tick UI installed in your project, learn the immediate-mode GUI model behind it, and create your first working screen.

This section is the front door for new users. Read in order:

1. Installation: get the package into your Unity project. Asset Store and Package Manager paths.
2. Introduction to immediate-mode GUI: the model behind Tick UI. What an immediate-mode GUI is and why it reads top-down.
3. Set up Tick UI: subclass BaseGameUI, write your first DoUI, and wire the render-pipeline integration onto your camera in the Inspector.
4. Build your first screen: a guided walk-through that combines layout, widgets, and panels into a working scene.
5. Set up AI assistance: wire up Claude Code or another AI coding assistant to use the package's CLAUDE.md, agent definition, API index, and cookbook from day one.
6. Compile flags: the scripting define symbols Tick UI recognises (TICK_URP, TICK_DEBUGGER, and the rest), set once in the asmdef or Player Settings.

After this section, the Core concepts pages cover the model in depth: the frame lifecycle, the stacks Tick UI maintains for you, and where state lives.
