-The Lean Core Library
-=========================
-
-The Lean core library is contained in the following files and directories:
-
-* [init](init/) : constants and theorems needed for low-level system operations
-* [init/logic.lean](init/logic.lean) : logical constructs and axioms
-* [init/data](init/data/) : concrete datatypes and type constructors
-* [init/algebra](init/algebra/) : algebraic structures
-
-Lean's default logical framework is a version of the Calculus of
-Constructions with:
-
-* an impredicative, proof-irrelevant type `Prop` of propositions
-* universe polymorphism
-* a non-cumulative hierarchy of universes, `Type 0`, `Type 1`, ... above `Prop`
-* inductively defined types
-* quotient types
-
-Most of the `core` library does not rely on any axioms beyond this
-framework, and is hence fully constructive.
-
-The following additional axioms are defined in `init`:
-
-* quotients and propositional extensionality (in `quot`)
-* Hilbert choice (in `classical`)
-
-Function extensionality is derived from the quotient construction, and
-excluded middle is derived from Hilbert choice. For Hilbert choice and
-excluded middle, use `open classical`. The additional axioms are used
-sparingly. For example:
-
-You can use `#print axioms foo` to see which axioms `foo` depends
-on.
