Documentation of built-in attributes and uniforms

Hello.

Can anyone point me to the location in the documentation that states what built-in attributes and uniforms are defined for vertex and fragment shaders? There is an archived version here: three.js docs but I cannot for the life of me find that info in the new documentation. I also cannot see it by making a delibarate compiler error in the shader. Only the user code is shown, not the three.js boilerplate.
