In the Project Manager click on the Top Schematic button, to open the Schematic editor:
You can then start placing parts by clicking the "Place Part" button in the top bar, or by simply typing p p (remember it as "Place Part"). This opens the Part Browser, where you can search your whole pool for the Parts you need and place them on the schematic.
Once you placed parts you can activate the "Draw net line" tool by typing n and drawing the connections. You can also simply drag out a pin and beginn connecting pins:
You can move parts and nets by selecting them and typing m or by using the ←/↑/↓/→ arrow keys. Rotate with r and mirror with e
If you forget any of these keys, just press Spacebar to open the :doc:`Spacebar Menu <spacebar-menu>` and search for the command you are looking for.

In the window that pops up press the "Add power net" button, give the net a name and select a symbol style.
Place power nets with the "Place power symbol" Tool (type p o).
Run the Annotation Tool to give all un-annotated parts (signified by the "?" in their reference designator) a propper number. So we go from this:
to this:
Once you are done, click on "Save" so you can start to layout the schematic you just created.
