# Simulator slugs

When using the *Simulators* tab in the c*oherence Hub*, you can enable the *Use Simulator* option and specify a *Simulator Slug*. This is simply a **unique identifier for a Simulator**. This value is automatically saved in `RuntimeSettings` when an upload is complete, and Room creation requests will use this value to identify which Simulator should be started alongside your room.

The Simulator slug can be any string value, but we recommend using something descriptive. If the same slug is used between two uploads, the later upload will overwrite the previous Simulator.

A list of uploaded Simulators can be found in the [Dashboard](https://coherence.io/dashboard), under the project's Schemas & Builds section.
