Base Nodes:

• Raymarch Input, ray origin and direction input, any raymarching shader should begin with this, as in example below

• Raymarch Process, this is where the magic happens,
  greatly simplified raymrching method in exchange for better performance.
  repeat this to get more accurate results (as in example below)

• Raymarch Post, computes useful data, like Normals, Position, Incoming, Reflection, UVs and Mask for your raymarched objects

• Scene, here you put your SDF objects, mix them using math nodes, and mix their UVs

• SDF Mix, used to mix between UVs and Colors inside Scene
