# Instantiating models
All Models can be found in the Domainrobot\Model namespace.
See an example of how to create a new model instance below:
use Domainrobot\Model\Certificate;
$certificateModel = new Certificate();
You can find a list of all available Models in our official Swagger documentation (opens new window) at the bottom of the page in the section Models.
Alternatively you can directly view the available models in the SDK source code here (opens new window).
