 The `rrule` returns the primal result `y`, and the pullback function.
 It is a _very_ good idea to name your pullback function, so that they are helpful when appearing in the stacktrace.
 ```julia
-    y = foo_mul(foo, b)
+y = foo_mul(foo, b)
 ```
 Computes the primal result.
 It is possible to change the primal computation so that work can be shared between the primal and the pullback.
 See e.g. [the rule for `sort`](https://github.com/JuliaDiff/ChainRules.jl/blob/a75193768775975fac5578c89d1e5f50d7f358c2/src/rulesets/Base/sort.jl#L19-L35), where the sorting is done only once.
 ```julia
-    function foo_mul_pullback(ȳ)
-        ...
-        return f̄, f̄oo, b̄
-    end
+function foo_mul_pullback(ȳ)
+    ...
+    return f̄, f̄oo, b̄
+end
 ```
 The pullback function takes in the tangent of the primal output (`ȳ`) and returns the tangents of the primal inputs.
 Note that it returns a tangent for the primal function in addition to the tangents of primal arguments.
 
 Finally, computing the tangents of primal inputs:
 ```julia
-        f̄ = NoTangent()
+f̄ = NoTangent()
 ```
 The function `foo_mul` has no fields (i.e. it is not a closure) and can not be perturbed.
 Therefore its tangent (`f̄`) is a `NoTangent`.
 ```julia
-        f̄oo = Tangent{Foo}(; A=ȳ * b', c=ZeroTangent())
+f̄oo = Tangent{Foo}(; A=ȳ * b', c=ZeroTangent())
 ```
 The struct `foo::Foo` gets a `Tangent{Foo}` structural tangent, which stores the tangents of fields of `foo`.

 The tangent of the field `c` is `ZeroTangent()`, because `c` can be perturbed but has no effect on the primal output.
 ```julia
-        b̄ = @thunk(foo.A' * ȳ)
+b̄ = @thunk(foo.A' * ȳ)
 ```
 The tangent of `b` is `foo.A' * ȳ`, but we have wrapped it into a `Thunk`, a tangent type that represents delayed computation.
 The idea is that in case the tangent is not used anywhere, the computation never happens.
