+    <h2>How To Use</h2>
+    <p><mark>Basic Usage:</mark> Use the mouse or your keyboard to input numbers and operators. Press "C" to clear the display, "=" to calculate  and "Enter" to calculate as well.</p>
+    <p><mark>Keyboard Shortcuts:</mark></p>
+    <ul>
+        <li><mark >Numbers (0-9):</mark> Type the number keys to input the respective numbers.</li>
+        <li><mark>Operators (+, -, *, /):</mark> Type the operator keys to input the respective operators.</li>
+        <li><mark>Enter:</mark> Calculate the result.</li>
+        <li><mark>Escape:</mark> Clear the display.</li>
+        <li><mark>Backspace:</mark>Delete one element.(Note it will not take one step backward)</li>
+        <li><mark>CAUTION:</mark>If using keybord buttons avoid placing mouse cursor. <br>This is a basic calculator uncapable of various functions and complex calculation.</li>
