Click the color you want to use as your shape's outline. If you want to fill the shape with a color rather than just drawing the outline of the shape, click the "Color 2" box and then click the color you want to use for the fill color. In the "Shapes" section of the toolbar, scroll up or down to see all of the available shapes. Click the shape you want to use to select it. Click Size, then click the line thickness you want to use in the resulting drop-down menu. By default, the shape's outline will be the same color as the "Color 1" box; if you want to change the consistency of the color or remove it entirely, click the Outline drop-down box, then click an option (e.g., No outline) to apply it. If you selected a "Fill" color, you can add the "Fill" option to your shape: click Fill, then click Solid color. You can select a different "Fill" option (e.g., Crayon) to use a stylized fill texture. This will draw your shape. Once the shape fits the size and location you had in mind, release the mouse button and click outside of the Paint canvas.
