+Kind2
+=====
+
+**Kind2** is a **functional programming language** and **proof assistant**.
+
+It is a complete rewrite of [Kind1](https://github.com/kindelia/kind-legacy), based on
+[HVM](https://github.com/kindelia/hvm), a **lazy**, **non-garbage-collected** and **massively parallel** virtual
+machine. In [our benchmarks](https://github.com/kindelia/functional-benchmarks), its type-checker outperforms every
+alternative proof assistant by a far margin, and its programs can offer exponential speedups over Haskell's GHC. Kind2
+unleashes the [inherent parallelism of the Lambda
+Calculus](https://github.com/VictorTaelin/Symmetric-Interaction-Calculus) to become the ultimate programming language of
+the next century.
+
+**Welcome to the inevitable parallel, functional future of computers!**
+
+Examples
+--------
+
+Pure functions are defined via equations, as in [Haskell](https://www.haskell.org/):
+
+```javascript
+// Applies a function to every element of a list
+map <a> <b> (list: List a) (f: a -> b) : List b
+map a b Nil              f = Nil
+map a b (Cons head tail) f = Cons (f x) (map tail f)
+```
+
+Side-effective programs are written via monadic monads, resembling [Rust](https://www.rust-lang.org/) and [TypeScript](https://www.typescriptlang.org/):
+
+```javascript
+// Prints the double of every numbet up to a limit
+Main : IO (Result () String) {
+  ask limit = IO.prompt "Enter limit:"
+  for x in (List.range limit) {
+    IO.print "{} * 2 = {}" x (Nat.double x)
+  }
+  return Ok ()
+}
+```
+
+Theorems can be proved inductivelly, as in [Agda](https://wiki.portal.chalmers.se/agda/pmwiki.php) and [Idris](https://www.idris-lang.org/):
+
+```javascript
+// Black Friday Theorem. Proof that, for every Nat n: n * 2 / 2 == n.
+black_friday_theorem (n: Nat) : Equal Nat (Nat.half (Nat.double n)) n
+black_friday_theorem Nat.zero     = Equal.refl
+black_friday_theorem (Nat.succ n) = Equal.apply (x => Nat.succ x) (black_friday_theorem n)
+```
+
+For more examples, check the [Wikind](https://github.com/kindelia/wikind).
+
+Usage
+-----
+
+First, install [Rust](https://www.rust-lang.org/tools/install) first, then enter:
+
+```
+cargo install kind2
+```
+
+Then, use any of the commands below:
+
+Command    | Usage                     | Note
+---------- | ------------------------- | --------------------------------------------------------------
+Check      | `kind2 check  file.kind2` | Checks all definitions.
+Eval       | `kind2 eval   file.kind2` | Runs using the type-checker's evaluator.
+Run        | `kind2 run    file.kind2` | Runs using HVM's evaluator, on Rust-mode.
+To-HVM     | `kind2 to-hvm file.kind2` | Generates a [.hvm](https://github.com/kindelia/hvm) file. Can then be compiled to C.
+To-KDL     | `kind2 to-kdl file.kind2` | Generates a [.kdl](https://github.com/kindelia/kindelia) file. Can then be deployed to [Kindelia](https://github.com/kindelia/kindelia).
+
+Executables can be generated via HVM:
+
+```
+kind2 to-hvm file.kind2
+hvm compile file.hvm
+clang -O2 file.c -o file
+./file
+```
