# Targets

Select a target with `--platform.name`. Its registry definition supplies memory capacities, alignment and capabilities for planning and kernel selection. Run `helia-aot list-targets` to inspect your installed version.

Reserve application space with [memory constraints](https://ambiqai.github.io/helia-aot/guide/memory-placement/#constraints). Registry capacities are the totals a program links into and reserve nothing for the application; registration alone does not establish hardware validation. For custom definitions, follow the [target guide](https://ambiqai.github.io/helia-aot/guide/targets/#overriding-a-platform).
