connect the Texture Node to the input socket of your Diffuse BSDF
(Figure 5.10).

The result will be a texture assigned to the material. Any Shader with an
input socket receiving color data (Yellow) will connect with the Image
Texture Node.
5.3.1 Projection for image textures
Each image you use in a material has an option for the projection type,
which affects how it appears in any 3D object. The projection options are
available at the Image Texture Node, and by default, will always start as
"Flat." That means your image will look good on bidimensional surfaces
like planes (Figure 5.11).
