Collaboratory.Lab
The Lab gives you the ability to develop and run programs in a browser, without needing to install anything on your local machine. These programs will then be run on the EBRAINS servers. The Lab works by giving you access to a JupyterLab service and the ability to create notebooks. A notebook is where you put your code which is executed when you press run.
You can access JupyterLab from the Lab navigation element in every collab (As long as you have permissions). Once you have clicked on the Lab, you will see all of the notebooks you have access to, more instructions can be found in the Tutorial section
