Hi! Something about tessaract?

Hi!
Someone said that I should install a program called tessaract. It seemed to find some package when i apt-get the tessaract-ocr but I find no way of opening it, tried tessaract from terminal, tessaract-ocr and on menu screen. How does it work? Or if anyone can recommend any other OCR readers that takes like whatever text in somewhat format and convert to readable text :slight_smile:
Thanks!
