+## Building
+cpp-spline comes bundled with sln and vcxproj files so that it can be directly opened and built using Visual Studio in windows.
+
+
+cpp-spline can now be build using cmake as well.
+
+Cmake can be installed in debian based systems by 
+
+```bash
+	sudo apt install cmake 
+```
+### Build instructions (linux)
+```bash
+     	git clone https://github.com/chen0040/cpp-spline.git
+       	mkdir build
+       	cd build
+       	cmake .. 
+       	make all
+       	./spline_app
+```
