Hi, this is my first post so please be kind to me

I have downloaded the tweakr 0.0.12-3 file to my phone Nokia N900, is there a specific place to as to where this should be stored?

Currently it is stored in - file manager - Nokia N900 - docs

No previous history of Linux or maemo before so my posting will be those of one who could take a bit of time to get used to things so any help is greatly appreciated.
