+Dashes and underscores
+----------------------
+
+Nori will automatically convert dashes in tag names to underscores.
+For example:
+
+```ruby
+parser = Nori.new
+parser.parse('<any-tag>foo bar</any-tag>')  # => { "any_tag" => "foo bar" }
+```
+
+You can control this behavior with the `:convert_dashes_to_underscores` option:
+
+```ruby
+parser = Nori.new(:convert_dashes_to_underscores => false)
+parser.parse('<any-tag>foo bar</any-tag>') # => { "any-tag" => "foo bar" }
+```
