Coding in Unity: Introduction to Shaders

Learn about the shared base code both types of shader use - naming, properties and subshaders.

Learn what pragma directives are and how to use them.

Examples of the properties a shader can have: 2D, CUBE, Range(a, b), Color etc - all here: https://docs.unity3d.com/Manual/SL-Properties.html
