Is there any manual or DOC to know how to use

I allready install the toolbox… but… how to use it???

While the Toolbox was developed with the end user in mind, i.e. most of it should not require a manual, you can always look at the website, where every feature is extensively explained. In addition, you can click on the “Help” buttons to summon the offline help (which contains pretty much the same content as the website).
