+<p>
+  Lists are ordered collections of values.
+</p>
+<p>
+  <code>List</code> is a generic type, having a type parameter
+  for the type of values it contains. A list of ints has the type
+  <code>List(Int)</code>, and a list of strings has the type
+  <code>List(String)</code>.
+</p>
+<p>
+  Lists are immutable single-linked lists, meaning they are very efficient to
+  add and remove elements from the front of the list.
+</p>
+<p>
+  Counting the length of a list or getting elements from other positions in the
+  list is expensive and rarely done. It is rare to write algorithms that index
+  into sequences in Gleam, but when they are written a list is not the right
+  choice of data structure.
