+        <h3>Easy access to SIMBAD, NED and VizieR data</h3>
+        <p>We provide with helper functions to easily load SIMBAD, NED or VizieR data for a given region of the sky:
+        <ul>
+            <li><code>A.catalogFromSimbad(&lt;target&gt;, &lt;radius-in-degrees&gt;?, &lt;catalog-options&gt;?, &lt;successCallback&gt;?)</code> will return a Catalog instance with Simbad data of the requested region around the target. Target can be an object name, a position or an object <code>{ra: &lt;ra-value&gt;, dec: &lt;dec-value&gt;}</code>.</li>
+            <li><code>A.catalogFromNED(&lt;target&gt;, &lt;radius-in-degrees&gt;?, &lt;catalog-options&gt;?, &lt;successCallback&gt;?)</code> will return a Catalog instance with NED data of the requested region.</li>
+            <li><code>A.catalogFromVizieR(&lt;vizier-cat-id&gt;, &lt;target&gt;, &lt;radius-in-deg&gt;?, &lt;cat-options&gt;?, &lt;successCallback&gt;?)</code> will return a Catalog instance with data of the requested VizieR catalogue.</li>

         <h3>Creating a marker</h3>
         <p>A marker displays a position on the sky. Clicking on a marker will open a popup with a title and text set upon creation.</p>
         <p>Use <code>A.marker(ra, dec, {popupTitle: &lt;title of the popup&gt;, popupDesc: &lt;text (possibly HTML) for the popup&gt;})</code> to create a new marker. You can then add it to an existing Catalog.</p>
