# Configure Rooms ![Configuring rooms in the Developer Portal](/files/yhmOEl9lmS4ina9fDOIY) From the left sidebar, select 'Rooms'. On this page you can: * choose the regions you want to allow your rooms to be created in * enable Simulators for your Rooms * view a list of recently created Rooms ### Simulators From the Developer Portal, you can configure what size you want your simulator instances to be. To attach a simulator to a Room, send the \`simulator slug\` uploaded through the SDK with the Rooms creation request. When using the [PlayResolver](/0.7.4/api-reference/network-sdk/rooms.md#rooms-api) to create rooms, the simulator uploaded through the SDK is automatically assigned in the creation request. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
