If you're creating a theme with plans to share it on the [Hugo Themes website](https://themes.gohugo.io/) please note that your theme's demo will be available in a sub-directory of website and for the theme's assets to load properly you will need to create absolute paths in the templates by using either the [absURL](/functions/absurl) function or `.Permalink`. Also make sure not to use a forward slash `/` in the beginning of a `PATH`, because Hugo will turn it into a relative URL and the `absURL` function will have no effect.
A theme component can also provide its own [Configuration File](/getting-started/configuration/), e.g. `config.toml`. There are some restrictions to what can be configured in a theme component, and it is not possible to overwrite settings in the project.
In addition to the configuration file, a theme can also provide a `theme.toml` file that describes the theme, the author and origin etc. See [Add Your Hugo Theme to the Showcase](/contribute/themes/).
The [`.Hugo.Generator`](/variables/hugo/) tag is included in all themes featured in the [Hugo Themes Showcase](http://themes.gohugo.io). We ask that you include the generator tag in all sites and themes you create with Hugo to help the core team track Hugo's usage and popularity.
