+# Lagrange Playground
 Play around with lagrange interpolation online
+Live Version: https://eliasfleckenstein03.github.io/lagrange-playground/
+
+## Controls
+- Leftclick to add a point
+- Drag a point to move it
+- Drag to move screen
+
+## Algorithm
+The Lagrange Polynominal Interpolation Algorithm creates a polynomial that goes through all given points.
+It is described here: https://en.wikipedia.org/wiki/Lagrange_polynomial
