      <h1>Go Agile!</h1>
  
      <h3>Agile software development is a group of software development methods based on iterative and incremental
        development, where requirements and solutions evolve through collaboration between self-organizing,
        cross-functional teams. It promotes adaptive planning, evolutionary development and delivery, a time-boxed
        iterative approach, and encourages rapid and flexible response to change. It is a conceptual framework that
        promotes foreseen tight interactions throughout the development cycle.</h3>
  
      <p>
        In February 2001, 17 software developers met at the Snowbird, Utah resort, to discuss lightweight development
        methods. They published the Manifesto for Agile Software Development to define the approach now known as agile
        software development. Some of the manifesto's authors formed the Agile Alliance, a non-profit organization that
        promotes software development according to the manifesto's values and principles.

        Agile principles</h2>
      <p>The Agile Manifesto is based on twelve principles:
      <ol>
        <li>Customer satisfaction by rapid delivery of useful software
        <li>Welcome changing requirements, even late in development
        <li>Working software is delivered frequently (weeks rather than months)
