+Graphics Assignment2
+=========================
+
+Divyesh Jain - 20171171
+-------
+
+Controls
+-------
+* W - move the plane forward
+* A, D - increase and decrease roll of the plane
+* Q, E - increase and decrease yaw of the plane
+* Z, C - increase and decrease pitch of the plane
+* Left Click - fire missiles
+* Right Click - drop bombs
+* V -  toggle between different views (tower view, plane view, follow view, top view, helicopter view)
+* Mouse - to move view when using helicopter view
+
+Details
+------
+* An arrow above the plane leads to next checkpoint
+* Vicinity of volcanoes is no fly zone
+* Enemy missiles reduce health
+* Dashboard shows information about plane
