On top of [Hugo global configuration](https://gohugo.io/overview/configuration/), **Hugo-theme-learn** lets you define the following parameters in your `config.toml` (here, values are default).
Note that some of these parameters are explained in details in other sections of this documentation.
```toml

# Prefix URL to edit current page. Will display an "Edit this page" button on top right hand corner of every page.
# Useful to give opportunity to people to create merge request for your doc.
# See the config.toml file from this documentation site to have an example.
editURL = ""
# Author of the site, will be used in meta information
author = ""
# Description of the site, will be used in meta information
description = ""
# Shows a checkmark for visited pages on the menu
showVisitedLinks = false
# Disable search function. It will hide search bar
# Order sections in menu by "weight" or "title". Default to "weight"
ordersectionsby = "weight"
# Change default color scheme with a variant one. Can be "red", "blue", "green".
themeVariant = ""
```
