 - Line seed fill of generic polygons
 - Pineda's algorithm for triangle rasterization (min-max mechanism)
 
+After you start the application, read the information and pick one algorithm using keyboard key.
+
+Algorithms are based on user interaction (mouse), they are animated and can be stepped (E, S keys).
+
+Using the application should be at least a little bit intuitive, if you follow the text in the top-left corner of your application.

+Exit application using `escape` key.

 ### Build
 
+To build this application you need to have `g++` (or similar compiler) installed with C++17 support.
+Furthermore you ought to have `SDL2` and `SDL2_image` libraries in your computer.
+
+In Ubuntu, install `g++`, `libsdl2-dev` and `libsdl2-image-dev` packages.
+
+Then run `./build.sh` script. If compilation ends with success, run the `./icr-algo` application.
