Most of the frontend stuff is either located main/views/themes/yourtheme/ or in an extension. Since this is open-source, you are able to modify the html within the php files.
PM me or write here what it is specifically you want to change and I'll help you out.
Thank you very much for your help.
The stuff that I have to change are the following:
1. On the default theme on the home page, exactly before the footer, there are 4 step,
Search (with Fa-Icon and Description)
Choose (with Fa-Icon and Description)
Pay by cash or card (with Fa-Icon and Description)
Enjoy (with Fa-Icon and Description)
I would like to change all of them Titles and descriptions. (I tried to search in all the code but i didn't find them!)
2. I would like to change the footer section, After Powered by TastyIgniter, I need to add the Company Reg Number and few information.
3. I would Like to change the Title of the Page, I mean the typing thay says "Welcome to TastyIgniter"
Thank you very much for your time,
