There are 7 library parts: 1q, 2q, 3q, 4q/4q+, 5q/51+, classical, useful, and construction-kit.
The last part lets you construct your outlines of any circuit you wish.

In this example, illustrated with short gifs, a three-qubit circuit diagram is put together, saved to the scratchpad, and loaded from it.
| Prebuild 3 qubits initialization | By hand 3 qubits initialization |
|---|---|
| Drag and drop the wanted initialization gates, here it's three. | They could be assembled by the single qubit init gates when aligned properly. |
 |
 |
| Single qubit gate | Two qubit gate |
|---|---|
| Align the single qubit gate along with the init box, the alignment lines turn solid blue once the right position is met. | Now the two-qubit gate has to be aligned with the initialization and one qubit gate, again, the lines turn solid when it is aligned properly. |

| Measurement | Mathematical labeling |
|---|---|
| There are three different types of measurement boxes, here the one with no connector to the left is chosen to finish the diagram. | Labeling the diagram parts is possible even with latex notation, double click the box and put two doller signs $$ around the latex part. |

| Save to Scratchpad | Load from Scratchpad |
|---|---|
Diagrams or parts of diagrams can be saved to the personal scratchpad. Select the parts and click the + sign next to the scratchpad to save it. |
When clicking on the diagram in the scratchpad, the whole saved diagram appears again. |
