Feel free to add any useful comment or chunk of text or documentation to your component.
In the Documentation tab, you can add your text in the Comment field. Then, select the Show Information check box and an information icon display next to the corresponding component in the design workspace.
You can show the Documentation in your hint tooltip using the associated variable _COMMENT_, so that when you place your mouse on this icon, the text written in the Comment field displays in a tooltip box.
For advanced use of Documentations, you can use the Documentation view in order to store and reuse any type of documentation.
