+## Usage
+
+### Adding theme
+
+If you use git for managing your content, adding it as a submodule is
+straightforward:
+
+```sh
+git submodule add https://git.sr.ht/~huyngo/victor themes/victor
+```
+
+Then add it in the config:
+
+```toml
+theme = 'victor'
+```
+
+### Use for blog
+
+You should add `blog` to the list of categories of the section to get
+reverse-chronological feed.  RSS feed is currently not tested.
+
+### Use for book
+
+You should add `book` to the list of categories for every section of the book
+to get recursive table of content and breadcrumb navigation. Bread crumb is
+generated from the current page up to the furthest ancestor section that is a
+book, so you have to add that for *every* section of the book.  If your site
+consists of only book, you can set a theme-specific parameter to note that:
+
+```toml
+[params]
+OnlyBooks = true
+```
+
+RSS feed is currently not tested.
