+## Sidenotes
+
+Distill supports sidenotes, which are like footnotes but placed in the margin of the page.
+They are useful for providing additional context or references without interrupting the flow of the main text.
+
+There are two main ways to create a sidenote:
+
+**Using the `<aside>` tag:**
+
+The following code creates a sidenote with **_distill's styling_** in the margin:
+
+```html
+<aside><p>This is a sidenote using aside tag.</p></aside>
+```
+
+<aside><p> This is a sidenote using `&lt;aside&gt;` tag</p> </aside>
+
+We can also add images to sidenotes (click on the image to zoom in for a larger version):
+{% raw %}
+
+```html
+<aside>
+  {% include figure.liquid loading="eager" path="assets/img/rhino.png" class="img-fluid rounded z-depth-1" zoomable=true %}
+  <p>
+    F.J. Cole, “The History of Albrecht Dürer’s Rhinoceros in Zoological Literature,” Science, Medicine, and History: Essays on the Evolution of
+    Scientific Thought and Medical Practice (London, 1953), ed. E. Ashworth Underwood, 337-356. From page 71 of Edward Tufte’s Visual Explanations.
+  </p>
+</aside>
+```
+
+{% endraw %}
+
+<aside>
+  {% include figure.liquid loading="eager" path="assets/img/rhino.png" class="img-fluid rounded z-depth-1" zoomable=true %}
+  <p>F.J. Cole, “The History of Albrecht Dürer’s Rhinoceros in Zoological Literature,” Science, Medicine, and History: Essays on the Evolution of Scientific Thought and Medical Practice (London, 1953), ed. E. Ashworth Underwood, 337-356. From page 71 of Edward Tufte’s Visual Explanations.</p>
+</aside>
+
+Sidenotes can also contain equations and links:
+
+In physics, mass–energy equivalence is the relationship between mass and energy in a system's rest frame. The two differ only by a multiplicative constant and the units of measurement.
+
+<aside>
+  <p>This principle is defined by Einstein's famous equation: $E = mc^2$ <a href="https://en.wikipedia.org/wiki/Mass%E2%80%93energy_equivalence" target="_blank">(Source: Wikipedia)</a></p>
+</aside>
+
+**Using the `l-gutter` class:**
+
+The following code creates a sidenote with **_al-folio's styling_** in the margin:
+
+```html
+<div class="l-gutter"><p>This is a sidenote using l-gutter class.</p></div>
+```
+
+<div class="l-gutter">
+  <p> This is a sidenote using `l-gutter` class. </p>
+</div>

 ## Other Typography?
 
 Emphasis, aka italics, with _asterisks_ (`*asterisks*`) or _underscores_ (`_underscores_`).
