+# Windmill theme
+
+## About
+
+Windmill theme focuses on clean usable navigation for large documentation
+projects. It retains the state of the menu of pages and folders across page
+transitions, by keeping navigation to an iframe.
+
+It also implements a versatile search, featuring term highlighting, and both a
+quick dropdown and a full-page option that allows the user to come back to
+search results.
+
+Within pages, it uses the default mkdocs theme, including syntax highlighting.
+
+## Installation
+
+Install the Windmill theme using `pip`:
+
+``` sh
+pip install mkdocs-windmill
+```
+
+To install and get started with `mkdocs`, follow [MkDocs documentation](http://www.mkdocs.org/#installation).
+
+## Usage
+
+To use the Windmill theme installed via `pip`, add this to your `mkdocs.yml`:
+
+``` yaml
+theme: 'windmill'
+```
+
+If you cloned Windmill from GitHub:
+
+``` yaml
+theme:
+  name: null
+  custom_dir: '{INSTALL_DIR}/mkdocs_windmill'
+  # Copy settings from mkdocs_theme.yml, which is ignored by custom_dir themes.
+  static_templates: [404.html]
+  search_index_only: true
+  include_search_page: true
+```
+
+Note that it's important for there to exist a homepage, e.g. a top-level root element in mkdocs 1.0+:
+``` yaml
+nav:
+  - Home: index.md
+```
+
+See [Customization](customization.md) for a few extra configuration options
+supported by the Windmill theme.
