+Welcome to the Geometric Constructor
+
+You can use this program to model compass-and-straightedge geometric constructions
+Read more about it here: https://en.wikipedia.org/wiki/Compass-and-straightedge_construction
+
+The program provides you with two fixed points to start the construction
+
+You can use the following keyboard commands:
+
+Select: Select or deselect entities by clicking on them
+Delete: Delete selected entities
+
+0 / H : Hide selected entities or show all
+1 / P : Construct a new point on the intersection of two existing geometries
+2 / C : Construct a circle on two existing points. First select the center point, then select the radius
+3 / L : Construct a line on two existing points by selecting them
+
++ / - : Zoom in or out of view
+Arrows: Pan the view
+
+Made for the ICS3U programming course, June 2017
