NSIS - copy files and paste in instalation folder

Hello. I'm new in NSIS. I want to create window in setup application which copy files from a directory to the installation directory, but i don't know what sould do. I use HM NIZ Edit 2.0.3 and I did app by creator. Please help me.

To learn NSIS, start with examining NSIS\Examples\Example1.nsi and Example2.nsi. Find out what all commands do, using the command reference: http://nsis.sourceforge.net/Docs/Chapter4.html

Once you know what all the commands in those Examples do, and why, you will be well on your way to understanding NSIS. For your specific problem, you can use the CopyFiles command: http://nsis.sourceforge.net/Docs/Chapter4.html#4.9.3.2
