+# Manually Creating Documents
+
+Besides being able to parse documents, Oga also allows you to create documents
+manually. This can be useful if you want to dynamically generate XML/HTML.
+
+Documents can be greated in two ways:
+
+1. Full blown documents (using {Oga::XML::Document})
+2. XML fragments (using just {Oga::XML::Element} and the likes)
+
+For example, lets create a document with a specific encoding and a single
+element:
+
+    xml_decl = Oga::XML::XmlDeclaration.new(:encoding => 'UTF-16')
+    document = Oga::XML::Document.new(:xml_declaration => xml_decl)
+    element  = Oga::XML::Element.new(:name => 'example')
+
+    document.children << element
+
+If you now serialize this back to XML (by calling `document.to_xml`) you'd get
+the following XML:
+
+    <?xml version="1.0" encoding="UTF-16" ?>
+    <example />
+
+You can also serialize elements on their own:
+
+    element.to_xml
+
+This would output:
+
+    <example />
+
+## Adding/Removing Attributes
+
+The easiest way to add (or remove) attributes is by using {Oga::XML::Element#set}
+and {Oga::XML::Element#unset}. For example, to add an attribute:
+
+    element = Oga::XML::Element.new(:name => 'example')
+
+    element.set('class', 'foo')
+
+    element.to_xml # => "<example class=\"foo\" />"
+
+And to remove an attribute:
+
+    element.unset('class')
+
+## Modifying Text
+
+Modifying text of elements can be done in two ways:
+
+1. Adding {Oga::XML::Text} instances to the list of child nodes of an
+   {Oga::XML::Element} instance
+2. Using {Oga::XML::Element#inner\_text=}
+
+The second option is the easiest and recommended way of doing this. Usage is
+quite simple:
+
+    element = Oga::XML::Element.new(:name => 'p')
+
+    element.inner_text = 'Hello'
+
+    element.to_xml => "<p>Hello</p>"
+
+Special characters such as `&` and `<` are escaped automatically when calling
+{Oga::XML::Element#to_xml}.
