+## Guiding Principles
+
+> [The more your tests resemble the way your software is used, the more
+> confidence they can give you.][guiding-principle]
+
+We try to only expose methods and utilities that encourage you to write tests
+that closely resemble how your Vue components are used.
+
+Utilities are included in this project based on the following guiding
+principles:
+
+1.  If it relates to rendering components, it deals with DOM nodes rather than
+    component instances, nor should it encourage dealing with component
+    instances.
+2.  It should be generally useful for testing individual Vue components or
+    full Vue applications.
+3.  Utility implementations and APIs should be simple and flexible.
+
+At the end of the day, what we want is for this library to be pretty
+light-weight, simple, and understandable.
