Texture Nodes
All Textures
All textures workflow same as like in Blender. Just connect sockets desired locations.
Image Texture
To create Image Texture Node, just drag your image to Blender Node Graph Editor or create new Image Texture Node with Shift + A then drag your image to texture socket.

Limitations
High calculation needed textures:
- Noise Texture
- Voronoi Texture
- Musgrave Texture
Those textures are procedurally generated textures. That's why using them too much and in high settings will result so much calculations in gpu side. So be careful while using those textures.
