If you are willing to download the theme manually then give us your mail id we will send you the charity theme.
also for the page to look like our demo you will need to create a home page and set the template as home page from the page attribute options on the page editor.
Then you will also need to set up the static home page from dashboard > settings > reading > set static home page and select the home page you created > click on save changes.
If you are unable to set up the theme then send us your wordpress credentials (username and password) and your website link on [email protected] we will set the theme for you.
