By default all logs, traces & experiments are grouped in the default project. You can specify a project name when you initialize the Parea client. This will automatically create a new project with that name if it didn’t exist before. Note, that the name of the project is only allowed to contain alphanumeric characters, dashes and underscores. 
from parea import Parea

p = Parea(api_key=os.getenv("PAREA_API_KEY"), project_name='my-project')
You can toggle between projects on the platform by clicking on the project name in the collapsible sidebar on the left.
