title: Flask-bootstrap simple app not rendering bootstrap correctly
body: <p>I'm having some problems to get a simple flask app to use the flask-bootstrap package. </p>
  
  <p>Following the documentation I installed flask-bootstrap, created the 2 files below and this worked fine. The problem I'm facing is that when I access index.html in the browser I see only the text <em>bootstrap/base.html</em> returned and see no reference to the bootstrap css files when I view the source.</p>
  
  <p>Appreciate any guidance on what I am missing here.
  Thanks.</p>
  
  <p><strong>__init__.py</strong></p>
  
  <pre><code>from flask import Flask, render_template
  
  from flask.ext.bootstrap import Bootstrap 
  
  app = Flask(__name__)
  bootstrap = Bootstrap(app)
  
  @app.route("/")
  def homepage():
      return render_template('index.html')
  
  if __name__ == "__main__":
      app.run(debug=True)
  </code></pre>
  
  <p><strong>index.html</strong></p>
  
  <pre><code>{% extends "bootstrap/base.html" %}
  {% block title %}This is an example page{% endblock %}
  
  {% block navbar %}
  &lt;div class="navbar navbar-fixed-top"&gt;
    &lt;!-- ... --&gt;
  &lt;/div&gt;
  {% endblock %}
  
  {% block content %}
    &lt;h1&gt;Hello, Bootstrap&lt;/h1&gt;
  {% endblock %}
  </code></pre>
