About themes
Gatsby has the ability to shadow code. It's awesome! To do this, you can overwrite any module/package file's that live
inside the src/ directory.
Overriding
To override a specific file, copy the file you wish to change to src/my-module/file.js (obviously changing the module
and filename to match the override) and then restart your server.
