+		    HYPERSPACE NAVIGATOR is a game about designing trajectories using <a href="https://tutorial.math.lamar.edu/Classes/CalcII/ParametricEqn.aspx">parametric curves</a>. These are curves where <strong>y</strong> is not determined by some function of <strong>x</strong> (e.g. <strong>y = f[x]</strong>), but where both <strong>x</strong> and <strong>y</strong> are determined by a third quantity <strong>t</strong>, which we might think of as time.
+		    Parametric curves are capable of producing complex and beautiful shapes from relatively simple definitions, and I encourage you to play with the system to see what you can create!
+		  </p>
+		  <p class="normal">
+		    While defining your parametric curves, you have access to the following operations:
+		  </p>
+		  <ul class="normal">
+		    <li>Addition (t+2)</li>
+		    <li>Subtraction (2-t)</li>
+		    <li>Multiplication (2t or 2*t)</li>
+		    <li>Division (t/2)</li>
+		    <li>Exponents (t^2)</li>
+		    <li>Modular arithmetic (t mod 2 or t % 2)</li>
+		    <li>Trigonometric functions (tan, sin, cos, acos, asin, atan, atan2)</li>
