## [When to use it](#when)

Use it to add tunable values or change starting values without touching the graph logic.

## [Example prompts](#examples)

Type requests like these in the Dola chat:

- Add a float MaxHealth = 100 to BP_Enemy and make it editable per instance.

- Set the default WalkSpeed in BP_Player to 450.

## [What you need](#requirements)

- The Dola desktop app, signed in, with your Unreal project attached

- Unreal Editor open on that project with the Dola plugin enabled (current builds: UE 5.7)

## [Safety notes](#safety)

- Edits are made in the open editor, then the Blueprint is compiled and saved so you can review the result straight away.

- Create a checkpoint before large changes so you can roll back what Dola wrote.
