### Creating Worlds

Click the *Create a World* button at the top right of the *Worlds* view in the Developer Portal.

![The New World form](/files/x4Lsx2OUVjy9vB1lLnwU)

To create a World:

* Enter a unique name
* (optional) choose an SDK version. The latest version is recommended, but this should match the SDK version installed for your project
* Enter tags separated by commas
* Choose which region the World should be started in
* Choose the size of the Replicator
* (optional) Choose the schema this World should start with. Usually, the latest schema uploaded is the preferred choice, and this is the default.
* (optional) Adjust the packet frequencies for sending and receiving data. It can be adjusted per project and is part of the *Advanced Config* section. Note that the adjustment of frequencies is accessible only for paid plans.

### Provisioning

The state of the World is automatically managed by default. Inactive Worlds with no connected players are suspended and then resumed when there are players online. Suspended Worlds retain their state and it only takes seconds to bring them back up and running.

{% hint style="success" %}
This feature can **reduce costs significantly** so we recommend keeping it on.

However, it is possible to turn it off by visiting the *Advanced* section of the *World Configuration* page.
{% endhint %}

{% hint style="warning" %}
The autoprovisioning feature can only be **turned off** if you have a **paid tier** **subscription**. It is always enabled for running Worlds for customers on the free plan.
{% endhint %}

### Joining an existing World in Unity

Please refer to the [Cloud Service API: Worlds](/1.0/coherence-cloud/using-coherence-cloud-in-unity/worlds.md) section\*\*.\*\*
