Need installation and first-use tutorial for Spreadsheet

I woudl like to try to use dhtmlxSpreadsheet but have found eth basic installation and first-use from the download (Standard Edition (full package) v.2.0) to be semi-unintelligible.

1)Downloaded and unpacked the zip file
2)Tried to use the Spreadsheet/index.html

Please, try to use the guides from the dhtmlx documentation:
docs.dhtmlx.com/doku.php?id=dhtm … sheet:init

here is the index page:
docs.dhtmlx.com/doku.php?id=dhtm … heet:start
