+### Generating Maps
+
 When creating a new map object, you can specify a set of options.
 
 ```ruby
 map = XmlSitemap::Map.new('mydomain.com', options)
 ```
 
 Available options:
 
-- :secure - Will add all sitemap items with https prefix. *(default: false)*
-- :home   - Disable homepage autocreation, but you still can do that manually. *(default: true)*
-- :root   - Force all links to fall under the main domain. You can add full urls (not paths) if set to false. *(default: true)*
-- :time   - Provide a creation time for the sitemap. (default: current time)
-- :group  - Group name for sitemap index. *(default: sitemap)* 
+- `:secure` - Will add all sitemap items with https prefix. *(default: false)*

+### Render Engines
 
+XmlSitemap has a few different rendering engines. You can select one passing argument to `render` method. 
+
+Available engines:
+
+- `:string` - Uses plain strings (for performance). Default.
+- `:builder` - Uses Builder::XmlMarkup.
+- `:nokogiri` - Uses Nokogiri library. Requires `nokogiri` gem.
+
+### Sitemap Indexes
+
 Regular sitemap does not support more than 50k records, so if you're generating a huge sitemap you need to use XmlSitemap::Index.
 
 Index is just a collection of links to all the website's sitemaps.
