 Another addition is the ability to enable the "HTML mode" for the Button component. In this mode, the button's action occurs in the context of `user action`, allowing operations like "copy and paste text" "show the keyboard" and more. However, in this mode, the button only responds to regular clicks due to the technical implementation of it (so no double clicks or long taps).
 
+The huge work was done on documentation. Now it's more clear and have more examples. All documentation now moved to the API section. The separate `componentd.md` file will be deleted soon as all documentation will be moved to the API section.
+
+The API section now filled with overview and usage examples. I've started with the basic modules, in future I will add more examples for all modules.
