          <h2 class="header">Future</h2>
          <p>Exercism is still a prototype, and we're still experimenting with the basic feature set. The goal is to develop a V1 of the product from scratch using everything that we've learned building and using the prototype.</p>
          <p>The V1 will be built using well-known frameworks and conventions to make the barrier to contributing as low as possible.</p>
