+  Gleam doesn't have loops, instead iteration is done through recursion, that is
+  through top-level functions calling themselves with different arguments.
+</p>
+<p>
+  A recursive function needs to have at least one <em>base case</em> and at
+  least one <em>recursive case</em>. A base case returns a value without calling
+  the function again. A recursive case calls the function again with different
+  inputs, looping again.
+</p>
+<p>
+  The Gleam standard library has functions for various common looping patterns,
+  some of which will be introduced in later lessons, however for more complex
+  loops manual recursion is often the clearest way to write it.
+</p>
+<p>
+  Recursion can seem daunting or unclear at first if you are more familiar with
+  languages that have special looping features, but stick with it! With time
+  it'll become just as familiar and comfortable as any other way of iterating.
