The link will return you to the project page of, and you will be ready to create your first project.

1.1 Create a New Project in Blues Notehub

Projects are core to the functionality of Notehub. They provide a way to organize group of products, distribute firmware, organize teams, and provide team access controls.

A Project is composed of one or more identifiers called ProductUIDs. Each Project is created with an initial ProductUID, enabling you to associate your Notecard(s) to your Project as soon as it is created.

i) Navigate to "io" domain, and click on the ‘Create Project’ button in the upper right corner.

ii) The ‘Create Project’ dialog will open.

iii) Provide a name for the project in the ‘Project Name’ input box.

iv) Provide a unique identifier for the default ‘ProductUID’. In order to help ensure your ProductUID is unique, every ProductUID is prepended with the reverse domain name notation of your account email.

v) For example, if you have signed up with [email protected], then your product would take the form of com.oceania.winston.smith :your_product_uid.

vi) Click the ‘Create Project’ button.

1.2 Create new Fleet

i) Select ‘Fleets’ from the left navigation bar.

ii) Click the ‘Add fleet’ option, in the upper right corner.
