During the registration process, you will be asked to create an Organization and a Workspace, to create a working environment. You can also create your environment at a later stage.
An Organization is an account where a business can collaborate across many workspaces at once. To create an Organization select "Add Organization" on the menu, on the upper right side.
Fill in all relevant information about your Organization. The Organization name is most likely your company name.
Workspaces are where the actual work happens: Adding Data Flows, Rules or managing devices - all activities are done within a workspace.
Once you have created an Organization, you will get asked to create a Workspace automatically. Fill in all relevant information about your Workspace. A suitable Workspace name is for example the name of your project. Proceed now with selecting "Create Workspace".
Congratulations, you have successfully created your first working environment!
