        As soon as you've submitted a solution to an exercise, the next exercise becomes available via the command-Line client.
        </p>
        <p>
        A lot of websites will let you download by clicking on a link, and submit by copying and pasting into a web form and clicking a button. Exercism doesn't have this type of interface. On Exercism, you download exercises and submit solutions back to the site via the command-line.
        </p>
  
        <p>
        In order to do this, you need to install the CLI.

        <p>You'll see references to <b>Command-Line Client</b>, <b>Command-Line Interface</b> and <b>CLI</b>. These all mean the same thing. They are generic terms for programs/tools that are meant to be used on the command-line.</p>

          Using Exercism requires three tools:
        </p>
  
        <ol>
          <li><strong>Your text editor</strong>: Write a solution to an exercise using your favorite text editor.</li>
          <li><strong>Your command line interface</strong>: Fetch problems and submit solutions via the command line (or terminal).</li>
          <li><strong>The <a href="http://exercism.io">exercism.io</a> website</strong>: Review feedback on your solution and discuss it with other learners on the website.</li>
        </ol>
