Download a copy of Casper
To start, grab a copy the latest version of Casper, the default theme pre-installed with Ghost.
Extract the theme files
Extract the theme folder from the compressed file to a location on your computer that you can work from.
Open the theme’s default.hbs file
Once you’ve extracted, find and open the default.hbs file in your HTML editor.
Locate the copyright information code
Now that you’ve opened the default.hbs file, scroll down towards the bottom of the file. You should see a piece of code that looks similar to this:
Update the code
Once you’ve located the copyright code, you can edit and format it (or delete it entirely) to suit your needs. For example, you may want to remove the link to Ghost, or remove your RSS information. Anything you change here will update across the bottom of your entire website.
Save your default.hbs file
After you’ve updated your copyright information, save the file.
Upload your theme
Now that you’ve saved your theme, you can then upload it to your blog. Once uploaded, your new copyright notice information will be reflected immediately.
