# rename()

Renames this layer. The text in the layer panel changes with it.

Avoid an empty name, or a name another layer already uses. Do not overwrite the system layer names `[Base]`, `[Cache]`, `[Export]`, and `[Fallback]`.

### Signature
```python
layer.rename(new_name) -> None
```

### Example
```python
layer = api.layer("Layer 1")
layer.rename("Arm")
print(layer.name)
```
