 # Happy Coloring Book
-Happy coloring book written in Java.
+Coloring book application for *every* system where Java SE is available.
+
 ## Description
 Work in progress. Very similiar application like in my xmas-colorbook repository.
-I will place more detailed description when i will draft a release.
+
+Some important things to notice:
+* Application currently does not offer any builded-in images to coloring - I am planning to make some few in future,
+but for now you must download some nice images to coloring for your own.
+* If you are curious where it make its autosave - look for ".HappyColoring" directory in your user home dir (just
+you must enable "show hidden files" in your file manager). Yes, I know most of people here would thinked this
+very fast, but I also know some who was a bit confused.
+* Yes this program can easily get foolished if you use two or more images with exactly the same name (even when they are
+in separate directories). Maybe it is bad idea to make such autosave feature, but for now it simply works like that and
+simply look at names of your coloring images - rename one if you have problems.
+* Mouse wheel works as a darkening or lightening current color.
+* Right mouse button works as a pipette tool - right click to get color from place under cursor.
+* Application currently have two language versions - english and polish (and they are not 100% finished yet).
