A new project can be created by clicking on Create project under MyQI. This will bring up a new form where you are asked to fill in a new project name and description that you would like to use for your project.
In your project you can add multiple quantum algorithms, by clicking on Create algorithm.
We can start by adding the Hello World example from the introduction. When you added a new algorithm, it will be empty. The file will be called source.cq. Click on the filename on the left to open the (empty) editor. Now you can copy and paste your algorithm here, or you can edit your own algorithm.
You can add more algorithms as part of this project or you can go to My QI and add new projects, which will make it easier to manage your work.
You can toggle the view of your algorithm (horizontal, on/off, vertical) with the buttons at the bottom right.
