+    <h2>Create Course</h2>
+    <p>
+      This page includes a simple todo list application, which showcases the
+      state management and form capabilities of vue.
+    </p>
+
+    <form @submit.prevent="createTodo" class="create-todo">
+      <label for="todo">New Todo</label>
+      <input type="text" id="todo" name="todo" v-model="newTodo" />
+      <button type="submit">Save</button>
+    </form>
+
+    <ul>
+      <!--
+        v-for requires a unique key for every element so that it can efficiently keep track
+        of each list item. it is possible for the user to type the same todo more than once,
+        so the todo itself isn't necessarily unique. the index on its own is of course unique,
+        it represents each unique place in the array. there are unfortunately edge case issues
+        with using the index alone that we don't need to get into, so we combine the todo and
+        the index into a unique key that will work in all situations
+      -->

+
+      <!--
+        it is a good user experience practice to provide feedback when in an "emtpy state",
+        in this case, where there are no todos to show yet. this informs the user of
+        the current status of the system (working), and doesn't make them wonder if something
+        has gone wrong
