 Usage
 ======
 
-Use it like this, simple.
+Add "bootstrapform" to your INSTALLED_APPS.
 
-.. code-block::
+At the top of your template load in our template tags::
 
-   {{ form|bootstrap }}
+	{% load bootstrap %}
+
+Then to render your form::
+
+	<form role="form">
+	    <legend>Form Title</legend>
+	    {% csrf_token %}
+	    {{ form|bootstrap }}
+	    <div class="form-group">
+	      <button type="submit" class="btn btn-primary">Submit</button>
+	    </div>
+	</form>
+
+You can also set class="form-vertical" on the form element.
+
+To use class="form-inline" on the form element, also change the "|boostrap" template tag to "|bootstrap_inline".
+
+It is also possible to create a horizontal form. The form class and template tag are both changed, and you will also need slightly different CSS around the submit button::
+
+	<form class="form-horizontal">
+	    <legend>Form Title</legend>
+	    {% csrf_token %}
+	    {{ form|bootstrap_horizontal }}
+	    <div class="form-group">
+	      <div class="col-sm-10 col-sm-offset-2">
+	      	<button type="submit" class="btn btn-primary">Submit</button>
+	      </div>
+	    </div>
+	</form>
