+Explanation: A function can return an output "term" that has a given "type",
+like this:
+
+
+    ┌────────────────────┐
+    │ ∀(x : Text) → Bool │  This is the type of a function that returns an
+    └────────────────────┘  output term that has type ❰Bool❱
+                    ⇧
+                    This is the type of the output term
+
+
+    ┌────────────────┐
+    │ Bool → Integer │  This is the type of a function that returns an output
+    └────────────────┘  term that has type ❰Int❱
+             ⇧
+             This is the type of the output term
+
+
+... or a function can return an output "type" that has a given "kind", like
+this:
+
+    ┌────────────────────┐
+    │ ∀(a : Type) → Type │  This is the type of a function that returns an
+    └────────────────────┘  output type that has kind ❰Type❱
+                    ⇧
+                    This is the kind of the output type
+
+
+    ┌──────────────────────┐
+    │ (Type → Type) → Type │  This is the type of a function that returns an
+    └──────────────────────┘  output type that has kind ❰Type❱
+                      ⇧
+                      This is the kind of the output type
+
+
+Other outputs are $_NOT valid, like this:
+
+
+    ┌─────────────────┐
+    │ ∀(x : Bool) → x │  ❰x❱ is a "term" and not a "type" nor a "kind" so the
+    └─────────────────┘  output cannot have "type" ❰x❱ or "kind" ❰x❱
+                    ⇧
+                    This is not a type or kind
+
+
+    ┌─────────────┐
+    │ Text → True │  ❰True❱ is a "term" and not a "type" nor a "kind" so the
+    └─────────────┘  output cannot have "type" ❰True❱ or "kind" ❰True❱
+             ⇧
+             This is not a type or kind
+
+
+You specified that your function outputs a:
+
+↳ $txt
+
+... which is neither a type nor a kind:
+
+Some common reasons why you might get this error:
+
+● You use ❰∀❱ instead of ❰λ❱ by mistake, like this:
+
+
+    ┌────────────────┐
+    │ ∀(x: Bool) → x │
+    └────────────────┘
+      ⇧
+      Using ❰λ❱ here instead of ❰∀❱ would transform this into a valid function
