+-- The Natural Numbers. These are constructed through:
+
+-- * `(0 : ℕ)`, an element called zero.
+-- * `(succ : ℕ → ℕ)`, the successor function , i.e. one is `succ 0` and two is `succ (succ 0)`.
+-- * `induction` (or `rcases`), tactics to treat the cases $n = 0$ and `n = m + 1` seperately.
+
+-- ## Game Modifications
+
+-- This notation is for our own version of the natural numbers, called `MyNat`.
+-- The natural numbers implemented in Lean's core are called `Nat`.
+
+-- If you end up getting someting of type `Nat` in this game, you probably
+-- need to write `(4 : ℕ)` to force it to be of type `MyNat`.

+
+-- ## Game-specific notes
+
+-- Note that you might need to manually specify the type of the first number:
+
+-- ```
+-- (2 : ℕ) ^ 1

+-- `False` is a proposition that that is always false, in contrast to `True` which is always true.

+-- ## Summary
+
+-- `rfl` proves goals of the form `X = X`.
+
+-- ## Details
+
+-- The `rfl` tactic will close any goal of the form `A = B`
+-- where `A` and `B` are *exactly the same thing*.
+
+-- ## Example:
+-- If it looks like this in the top right hand box:
+-- ```
+-- Objects:
+--   a b c d : ℕ
+-- Goal:
+--   (a + b) * (c + d) = (a + b) * (c + d)
+-- ```
+
+-- then `rfl` will close the goal and solve the level.
+
+-- ## Game modifications
+-- `rfl` in this game is weakened.
+
+-- The real `rfl` could also proof goals of the form `A = B` where the
+-- two sides are not *exactly identical* but merely
+-- *\"definitionally equal\"*. That means the real `rfl`
+-- could prove things like `a + 0 = a`.
+
+-- "
+
+
+-- TacticDoc rw
+-- "
+-- ## Summary
+
+-- If `h` is a proof of `X = Y`, then `rw [h]` will change
+-- all `X`s in the goal to `Y`s.
+
+-- ### Variants
+
+-- * `rw [← h]` (changes `Y` to `X`)
+-- * `rw [h] at h2` (changes `X` to `Y` in hypothesis `h2` instead of the goal)
+-- * `rw [h] at *` (changes `X` to `Y` in the goal and all hypotheses)
+
+-- ## Details
+
+-- The `rw` tactic is a way to do \"substituting in\". There
+-- are two distinct situations where use this tactics.
+
+-- 1) If `h : A = B` is a hypothesis (i.e., a proof of `A = B`)
+-- in your local context (the box in the top right)
+-- and if your goal contains one or more `A`s, then `rw [h]`
+-- will change them all to `B`'s.
+
+-- 2) The `rw` tactic will also work with proofs of theorems
+-- which are equalities (look for them in the drop down
+-- menu on the left, within Theorem Statements).
+-- For example, in world 1 level 4
+-- we learn about `add_zero x : x + 0 = x`, and `rw [add_zero]`
+-- will change `x + 0` into `x` in your goal (or fail with
+-- an error if Lean cannot find `x + 0` in the goal).
+
+-- Important note: if `h` is not a proof of the form `A = B`
+-- or `A ↔ B` (for example if `h` is a function, an implication,
+-- or perhaps even a proposition itself rather than its proof),
+-- then `rw` is not the tactic you want to use. For example,
+-- `rw (P = Q)` is never correct: `P = Q` is the true-false
+-- statement itself, not the proof.
+-- If `h : P = Q` is its proof, then `rw [h]` will work.
+
+-- Pro tip 1: If `h : A = B` and you want to change
+-- `B`s to `A`s instead, try `rw ←h` (get the arrow with `\\l` and
+-- note that this is a small letter L, not a number 1).
+
+-- ### Example:
+-- If it looks like this in the top right hand box:
+
+-- ```
+-- Objects:
+--   x y : ℕ
+-- Assumptions:
+--   h : x = y + y
+-- Goal:
+--   succ (x + 0) = succ (y + y)
+-- ```
+
+-- then
+
+-- `rw [add_zero]`
+
+-- will change the goal into `succ x = succ (y + y)`, and then
+
+-- `rw [h]`
+
+-- will change the goal into `succ (y + y) = succ (y + y)`, which
+-- can be solved with `rfl`.
+
+-- ### Example:
+
+-- You can use `rw` to change a hypothesis as well.
+-- For example, if your local context looks like this:
+
+-- ```
+-- Objects:
+--   x y : ℕ
+-- Assumptions:
+--   h1 : x = y + 3
+--   h2 : 2 * y = x
+-- Goal:
+--   y = 3
+-- ```
+-- then `rw [h1] at h2` will turn `h2` into `h2 : 2 * y = y + 3`.
+
+-- ## Game modifications
+
+-- The real `rw` tactic does automatically try to call `rfl` afterwards. We disabled this
+-- feature for the game.
