 # Any variable there can be overriden in the end user `config.toml`
 # You don't need to prefix variables by the theme name but as this will
 # be merged with user data, some kind of prefix or nesting is preferable
 # Use snake_casing to be consistent with the rest of Gutenberg

+
+## Working on a theme
+As a theme is just a site, you can simply use `gutenberg serve` and make changes to your
+theme, with live reloading working as expected.
+
+Make sure to commit every directory (including `content`) in order for other people 
+to be able to build the theme from your repository.
 
-- `static`: any static files used in this theme
-- `templates`: all templates used in this theme
-- `sass`: Sass stylesheets for this theme, can be empty

+## Submitting a theme to the gallery
+
+If you want your theme to be featured in the [themes](./content/themes/_index.md) section
+of this site, the theme will require two more things:
+
+- `screenshot.png`: a screenshot of the theme in action with a max size of around 2000x1000
 - `README.md`: a thorough README explaining how to use the theme and any other information
 of importance
 
-A simple theme you can use as example is [Hyde](https://github.com/Keats/hyde).
+The first step is to make sure the theme is fulfilling those three requirements:
 
-# Caveat
+- have a `screenshot.png` of the theme in action with a max size of around 2000x1000
+- have a thorough `README.md` explaining how to use the theme and any other information
+of importance
+- be of reasonably high quality
 
-Please note that [include paths](https://tera.netlify.com/docs/templates/#include) can only be used in used in normal templates. Theme templates should use [macro's](https://tera.netlify.com/docs/templates/#macros) instead.
+When your theme is ready, you can submit it to the [themes repository](https://github.com/Keats/gutenberg-themes)
+by following the process in the README.
