+# Hints
+
+## General
+
+- Use the built-in [(linked) list type][list].
+
+## 1. Define a function to return an empty language list
+
+- The function needs to return `[]`.
+
+## 2. Define a function to add a language to the list
+
+- An element can be prepended to a list using `|`.
+
+## 3. Define a function to remove a language from the list
+
+- Elixir [provides a function][tl] to return a list with the first item removed.
+
+## 4. Define a function to return the first item in the list
+
+- Elixir [provides a function][hd] to get the first item from a list.
+
+## 5. Define a function to return how many languages are in the list
+
+- Elixir [provides a function][length] to count the length of a list.
+
+## 6. Define a function to determine if the list includes a functional language
+
+- Your function should return a boolean value indicating whether `"Elixir"` is a member of the list. Elixir [provides a function][in] to test list membership.
