+ <h1>Installing RDKit on Google Colab</h1>
+
+<p>RDKit is one of the most integral part of any Cheminfomatic specialist's toolkit but it is notoriously difficult to install unless you already have <code>conda</code> installed. I originally found this in a GitHub Gist but I have not been able to find that gist again :/ </p>
+
+<p>Just copy and paste this in a Colab cell and it will install it 👍</p>
