Theme:Customizr

Hello everyone,
i am brand new user of cPanel, WP etc. I was building my website with WP although then I decided to edit a custom template which I ve finished it. Although still my main page is with WP and i want to change that. I edited one of WHMCS’s templates and now I just need to make that template appear in the main page and not only at the client area. Thank you so much for your time I m really looking forward for your response.
